Should Mention I don't use any other motion enhancements.
As far as BFI flickering, I don't really notice flickering in 60 & 24 fps content, but with 25fps the flicker is unbearable. It's probably because for 25fps the panel is running at 100hz instead of 120hz. For now I've been using a separate picture mode for 25fps.
Planning to get it calibrated down the road, but for now this is how I've compensated for BFI being darker.
-In SDR, you can just increase OLED and Contrast settings. Think I'm 100 OLED and 90 Contrast for the ISF modes.
-For Dolby Vision I find that "Cinema Home" with BFI looks the same as "Cinema" without BFI. (Flattened everything in VIVD for a daytime mode.)
-HDR10 is a little trickier because "Home" isn't brighter. For now I'm using Cinema mode with tone mapping on and dynamic contrast on low. On paper this sounds like a bad idea, but when I compare it to default cinema or technicolor with BFI off it looks pretty close to me.
I am curious about how calibrators find calibrating with BFI on.
This is just my experience. Know a lot of other people feel differently.
I've used a Panasonic 42Vt30 for the last couple of years and BFI was one reason why I opted for the rather more expensive C8 over last year's C7 (in addition to Dynamic Tone Mapping for Gamemode, which I consider something of a potential future-proofing feature of the TV, when presumeably more games will be mastered at more than 1,000 nits and HDR support will be standart).
I share your views on motion interpolation. I tried it on my C8 and while I think Sony and also Philips do a better job at this, it's still not something I can appreciate on any TV of any make (yet). It just looks "off" to me, even when the benefits in term of motion resolution are obvious and artificats are kept to a minimal (even low degrees of the dreaded soap opera effect bother me). It's a moot point though, as I've obviously become very sensitive to input lag over the last couple of years. I noticed it straight away, when I tried motion interpolation on my LG, which of course only works outside of Gamemode. I think the TV has a pretty high input lag then of something akin to 80ms and any game that is not like turn-based or anything (I tried it with Horizon Zero Dawn for instance) feels like you are moving through molasses ... it's unpleasant and more detracting than the motion resolution issue.
The beauty of LG C8 is that once you switch to Gamemode you are playing at around ~24ms I think and it definitely feels virtually indistinguishable from my Panasonic. It feels snappy and responsive, just right and exactly as I hoped - no issues there. The ONLY feature in terms of motion clarity in Gamemode is BFI and it works - to my understanding - as well as could be expected. It does not solve the issue and I still feel my Panasonic was quite a bit sharper, but it helps alot to address the issue of e.g. circles being drawn out into ovals and such when moving horizontally accross the screen (one "test" I run, is simply moving the Destiny 'selector' horizontal at max speed). It's hard to measure, but I think saying that it cuts the distortion, so to speak, in half, is actually pretty accurate.
Now, there are a couple of things to note here. In terms of flicker, I don't see on consoles, not at all, but I also never really saw it for my Plasma either, like never really. It can depend on the viewing conditions and the content though. I almost skipped the C8 as watching on the sales floor under their lighting running Pal TV content ... it was not pretty and the flicker was obvious. At home under my lighting, I can still see the flicker when I watch TV. I definitely would not recommend it then, if you watch a lot TV, because if you are anything like me you will definitely notice it there, and yeah, I find it distracting.
Now the other thing of note is that the price drop is quite significant. It depends on a number of factors I think, in terms of how much of a subjective impact it has, and there a few things you can do to address it, like pumping up the OLED Light and activating Dynamic Contrast (I know, but let me finish) ... the thing is, in terms of HDR content, you don't have the wiggle room left you can use for SDR content to mostly compensate for the subjective loss in brightness. This means, that if you play in HDR (again like Destiny 2) you will end up with a signficantly dimmer picture (I'd say it's "feels" like 15% or so, but don't take this an measurement, but just a gutfeeling, I have no way to ascertain it). It's obvious, but again though, DC helps and it's really the only time, where I find it to be of legitmate use. To make a real life example, in Destiny 2 I always turn on BFI for PvP/Crucible, but mostly leave it off for PvE (which I rarely do anyways) ^^ because it does detract from the sumptous HDR visuals the game has to offer, which in turn are not really the point of PvP, where they can actively even hinder you at times (like literally blinding you to enemies jumping in front of the sun and such).
I also felt that 60 fps games seem to benefit more in terms of gained clarity (like say Nioh as an SDR game in performance mode vs Destiny 2 a HDR running at 30 fps) over 30 fps games. That is also of concern seeing as right now, most fast action games (where this kind of motion clarity is of big concern) run at 30 fps, at least on consoles, be it PS4 Pro or Xbox One X. Speaking of XBX, I'd say that like Forza 7 does definitely benefit from BFI, although ... like I said, you do loose alot of brigthness in HDR mode. For something like Forza 6 though, running in SDR at 60 fps, I'd say BFI is a no-brainer.
Now, the same pretty much goes for movies. The benefit less in my view than 60 fps games, and for HDR you loose a significant amount of brightness. It's a steep trade-off to be honest and mostly, I don't use it for movies, and certainly not for HDR ones.
So, BFI is not perfect, as it still does not look (to me) as sharp as my old Pana Plasma and it comes at the cost of brightness, esp. in HDR mode, and it seems to be only real "ideal" for 60 fps SDR gaming content, where it really shines, while other uses always include severe trade-offs.
I think it really depends on your usage profile then. TV I'd say is a no-go, Movies is okay, but you will loose some of that HDR-WoW-Effect, Gaming can benefit greatly, depending on whether you are running 30fps or 60fps (at least that's my impression), and in terms of HDR, you face the exact same issue as with movies. For gaming it's the only option to do anything about motion though, as playing outside of gamemode, is really only enjoyable for games that are largely 'menu'-driven, generally slow, and certainly not dependend on fast reactions and timing.
I will also say though, that the deep black of the C8 blows my Pana Plasma out of the water, which I did not expect to be honest, even on SDR content like The Evil Within 2 (a very dark game, with plenty of you and your flashlight going about ^^), it looks incredible and like a significant upgrade. HDR itself is the absolute game changer here. Something like God of War looks truly magnificant, almost tears-of-joy inducing good. It's the singular leap I've witnessed since moving from my CRT to a Sony 1080p LCD back in the day. Is it worth it though then? For any HDR content, which will include probably all future AAA content, the answer is yes.
For SDR content ... well, yes and no. Something like the aforementioned TEW2, a very dark and atmosphere driven game that's also rather slow paced, yes, it's simply better on my OLED. If I compare it to say Overwatch though, where you don't gain anything in terms of HDR or resolution (the benefit of 4K to me, at least on a 55" is not enough to justify the purchase to be honest, and having seen the C6 65" for a long time at a friends now, I don't feel much different about that either - not compared to the bounds and leaps of HDR though), plus you are looking at a really bright and fast paced game, the Plasma was argueably the better choice.
So, yeah, consider your usage profile and also timing - aka not all games run in HDR yet (and some that do like Monster Hunter: World are broken). THe same goes for movies, if that is your vice. It will be some time, before the tech comes into it's full potential, so maybe just wait 2-3 more years. I'm sure motion handling will improve and HDR will be a default option, as it's slowly even coming to services like Netflix and such, if shows are your primary usage. If we are talking TV, then I'd say stick to your old set. At least around here, we are looking at 720p SDR content now and for the forseeable future as the default format, and in that regard, I feel like the OLED is more of a downgrade really, plues BFI causes visible flicker ...
I hope this helps, even though I am a bit late to the tread! :-)
