I ran a few forced compensation cycles because the light band I have in the middle-right (3rd quarter) of my screen was noticeable across a good amount of real content. After 2 forced compensation cycles, not much happened. On the 3rd, there was a major
improvement across the board in uniformity (third time's the charm?). It is now very difficult to spot even when looking for it in difficult scenes, and in most scenes it has disappeared. Yes, the first thing I did was to check that the black levels had not changed, using a couple test scenes that I use for consistency control. I did not need to make any adjustments, everything appears the same, and I also confirmed that Gamma and Black Level settings are still the same as well.
I will add that, before
I did any of the above 3 forced compensations, an automatic
compensation cycle (the one every 4 hours) caused my brightness to shoot through the roof. I had to drop it 16 points to get it back to the correct level. No idea what happened here. My brightness is now at 41 - not a typo - 41.

Does it only show up on dark sections or is the issue also present when it's brighter ? Does it cause DSE ?
It's a lot of cash to drop on a TV which would be fine if there weren't any big issues but this scares me a little.
Look at the photos here and take the mental average. Decide if it's acceptable for you. No one can tell you that; as you see VidPro is unhappy but others may not be. You can see photos of mine soon.
I've never noticed DSE or vignetting on mine in a pretty good variety of content so far. I cannot imagine spotting those kinds of issues in content, but the eye is more sensitive to the abrupt transitions brought on by banding non-uniformities.

I have a Samsung HU9000, and the fan bugs me a lot.
It is completely silent, on or off. Coil whine is extremely annoying but I have only ever gotten that from a graphics card.

About 1 inch. I took some photos but AVS is not letting me upload. 3 connectors go parallel to the wall; one goes out at the wall. The HDMI ARC port is one of the parallel ones.

I can understand waiting for VRR and Dynamic HDR.
But it does need to be said that some people get into this mode of thinking "its stupid to buy now, next year there will be <insert feature>". My brother is famous for this. You could make that argument for any year of the last two decades, and if you did, you'd have spent those two decades playing games on the original Nintendo. At some point you simply have to pull the trigger.
Maybe HDMI will announce HDMI 2.2 in early 2018 (at which point LG will probably have a nice visit at HDMI HQ and slap them upside the head).

Yep that's what I was going to suggest. There does appear to be multiple reports of people seeing large scale improvements from manual compensation cycles (HDTVTest also noted this). I had to run mine several times though before it did anything.
