Hi gomemphis. It's a fantastic projector in almost every respect - build quality, remote, calibration options, sharpness and color are amazing... The biggest drawback I already knew about is black levels. They are worse than the UHD65 by a fair amount.
When I first got it, I threw on my black level torture test blu-ray, Alien, and was shocked to discover the gray screen I was looking at was not a loading screen of some kind, but the actual film playing a black screen! I almost returned it right away, but then I did some more tweaking and found a pretty decent fix by putting it into "Smart Eco" mode on the lamp setting and adding a .3 (1 stop) ND filter in front of the lens. This cuts out half the light overall and the smart eco mode keeps the dark scenes darker while pumping up the light levels for brighter scenes. For my 100" screen, doing this and having it in THX mode is a solid amount of light. Also I turned on Brilliant Color and bumped up the contrast a bit. Then I tried out some brighter content and put on "One Strange Rock" on Netflix. Holy moly, the color and sharpness was on another level! I sit pretty close to the screen and there wasn't a pixel in sight, just a smooth, totally immersive image.
So I've hung onto it for now as my compromise that lands on the sharpness over contrast end of the spectrum. But every time I watch dark content, I'm quietly resolving to find another solution. Ever since being spoiled by a Sony OLED 4K TV, every projector I've tried ends up in a love/hate relationship.
THAT SAID, I've been following the reviews of the HT3550 quite closely and am likely going to order one to compare to the 8050 as soon as it becomes more readily available. It seems to have struck a great balance of decent contrast / black levels with good HDR performance and decent sharpness for $1,500. The new Epson 5050 also looks interesting, but I can't swing twice the price for what seems to be incremental benefit in contrast and potential loss in sharpness. The 8050 looks like a beast and is superb build quality that's sure to hold up for a long time, but if I were you, I'd check out the HT3550 first!
Hope this helps!
Side note on the 8050's dynamic iris. I tried it for a while and it seemed to work alright as long as you weren't using subtitles. But while watching Annihilation with a group recently the iris decided it would freak out randomly and introduce a bunch of flicker. I've vowed to never use it again, so I wouldn't count that as a plus towards this projector. Smart Eco lamp mode is a much more stable light throttle.
