Oof. A lot to unwrap here, but thanks for the opportunity.
RE: SDE:
I sit 7' from a 120" screen. I simulated that at a high-end dealer before pandemic for a 6040UB, and noticed it. BUT, I totally agree that it's really only relevant to people with eyesight that will catch it. I happen to be 20/15 in both eyes, so I catch it. You're right that this is not, and should not be purported to be, a problem for most people. I have known FAR more who suffer RBE than SDE.
RE: Motion handling:
I should have been more specific, as you cited exactly the type of programming where DLP does shine in terms of rendering. DLP still loses on brightness, so if someone wants sports or other fast-moving content to be brighter and is less concerned with sharpness, Epson wins that battle. I prefer sharpness, and I watch most of my team's NFL season (as well as the playoffs in general) on my projector--so that's relevant to me. Brightness for me on a 1080p projector has less and less of a concern as I continue to black out the dedicated space I have... but there's more on this later.
RE: Color accuracy
I didn't say it wasn't fine, and it's actually a mixed bag here; some natural hues are rendered better on the HT5550, while at the same time it proves to be a touch too warm in some scenarios. Scott's video definitely demonstrated that. Epson does a great job here.
RE: Brightness (again-ish)
Very interesting point is raised here. I admit, I hadn't looked enough at the fL the HT5550 would produce versus my current pj (HT3050). The HT5550 doesn't show up in the Web Projector Calculator, but does in Jack Liu's calculator, so I'll use that as a baseline:
Assumptions:
- Throw distance of 11'10"
- Screen fixed @ 120"
- Screen height @ 1.5' from floor
- Ceiling height @ 84"
- Distance for my seat @ 90"
- Gain 1.1 (typical Silver Ticket 120" fixed many have)
Results:
The HT3050 produces 30.9fL max, so given lamp age and zoom loss, probably low/mid-20's at this point. That matches my experience with it in the last 3 years. The HT5550 has a max fL of 27.8, and obviously decreases with time. The Epson (I know, this will shock you) is at 51.5fL--worth noting I had to use the 5040UB because it doesn't yet have the 5050UB, but if anything that just slightly handicaps the fL given the slight bump in lumens in the newer generation.
So if fL is champ, then I agree with you. For other projectors that can do DTM, that's a different story, but for the context of these projectors, it looks like you're spot-on.
Well, instead of getting 90 min of studying in for refreshing some AWS certs, I ended up learning a lot more about fL. 😆
RE: priorities
Contrast - UB better
Agreed
WCG - UB more and brighter
Agreed
Resolution - UB not a problem
This is more of a probability than a fact. For me, and I recognize I'm the corner-case, it's a challenge. Sports viewing also presents that challenge.
For the OP, the HT3550 / 5050UB comparison is odd, because the price difference in the US is huge if you take deals into consideration (about $1k USD in best deals I've seen). The closer comparison in terms of quality and price was HT5550 / 5050UB, but your points as to why 5050UB would generally take the cake are clear.
For
me, ideally, I'd be able to test out the 5050UB and swap to the HT5550 if I'm dissatisfied. But that's pretty complicated, since the best deal I found was on PG, and their return policy cites "unused", plus the shipping cost charge aspect. If I ended up with buyer remorse, I'd either be out of luck or looking at paying back the discount I got on the purchase to begin with. (The deal I'd wrangled was very attractive.) Guess it'll be more research for me.
It's about priorities, what is right for you. Personally if I were in your situation I would get the best CR model available, and move the seating backwards.
If you have a few hours you can research lumen measurements and will see that Gregory's DLP brightness measurements are abnormally high. Not sure why, probably has to do with technique. Over time I've come to know what sites are likely to be true with their measurements.
An 120" 16:9 screen is 42.71 ft². That fabric is 1.0 gain.
From 11'10" with both the HT5550 and 5050UB that's minimum throw.
From PC measurements, the HT5550 can do in Full lamp and Cinema preset 899 lumens with a new lamp.
Lamps loose ~25% brightness after ~500h.
899 / 42.71 = 21fL
674 (after 500h) / 42.71 = 15fL
On Vivid Brilliant Color is activated which color lumens stay the same as in Cinema, so lust 78%, with some color accuracy downgrade.
And yes, it does matter how bright color lumens are.
5050UB can do 1438 (color/white lumens) in Natural Cinema on Eco lamp.
1438 / 42.71 = 33fL
1078 (after 500h) / 42.71 = 25fL
Recommendation for SDR in a dark room is 15fL. For HDR it depends on the tone mapper. For JVC NX series I've seen 21fL recommendation. You can assume that for these two models it's more.
I do not believe the 15 000h on SmartEco for the HT5550 and others. If Benq really believes the lamp will last 15 000h why is the warranty for the lamp less then for the projector? It's usually 2000h or 1 year, whichever comes first.
ANSI CR vs. FOFO CR has been long debated, and almost everyone agrees that the FOFO spec is more important.
That's because most content is dark:
The same factor has been described by others on this forum, which they call "pop" and no one says LCOS or LCD had the pop factor that I only see described when talking about DLP or plasma. It's the extra sharpness and less dense pixel fill, generally speaking, it's not the ANSI contrast...

What % ADL looks like:
I'm sorry, but now we're back to subjective opinions again. It is quantifiable that two projectors, one high ANSI contrast, and one low ANSI contrast will measure different contrast levels when projecting the same bright, high contrast image. Factors other than ANSI contrast will obviously...

Measurement percentages aside, having a bad image will produce a larger bad impression then a number. Like a fly in a soup.
You can of course read the entire thread.
FOFO CR measures a black image and then a white image. The ratio between the two is the CR.
ANSI CR measures a black and white checkered pattern, taking the measurements for black and white off the same screen.
In actual content black level does not stay at the level it was measured with the FOFO CR, it climbs down in a gradient:
A study of the influence of the room and the projector on the resulting contrast performance. Examples with Sony VPL-VW520ES, Epson EH-TW9200 and Benq W1070

If you look at the example with the TW9200, which is the 5030UB in the US, which is practically the same as the 5050UB CR wise, you'll see that it performs much better than a 1080P DLP, the W1070, at low ADL.
Measurements taken by Projector Dream were without lamp dimming or iris.
Lamp dimming helps in a very small amount compared to irises.
Irises only work at ~1% ADL.
5050UB can do ~4500:1 native and ~37 000:1 dynamic (FOFO).
HT5550 can do ~700:1 native and ~6000:1 dynamic (iris).
HT3050 can do ~1500:1 native and ~2000-2500:1 dynamic (lamp).
That is a massive difference.
You can take Projection Dream's table and extrapolate what CR would look like at % ADL with the iris. It makes a huge difference at low ADL, where a lot of content is at.
This is a measurement of GoT S03.E10:
If a scene has a bright object next to a dark one models with better ANSI CR are supposed to do better, like with a star field. But in practice that's not true. Whatever advantage models with better ANSI CR, it's very minor compared to the black level of models with proper FOFO CR.
Here's what a knowledgeable person had to say about this:

I also have an W2000 (HT3050) in a semi treated room with an ALR screen, and am not happy with low ADL performance. This model has a higher ANSI CR then others (~530:1), but low ADL scenes with bright/dark objects still look disappointing
From my experience and what others have said it's pretty clear that models that can do low black level (high FOFO CR) are better then those who can do high ANSI CR.
Also while some people on this forum say what they believe, some do it for money. It's a good idea to do research and judge accordingly.
