You are killing me mannnn. Guess what !!!! I am going to order one now. Ok so the images you post are jaw dropping. No doubt. Are these 1080P upconverted or 4K images? If its 4K then may be not an apple to apple comparison. I better comparison would be to post a 1080P movie image upconverted (if you don't mind).
Also what screen gain and size are you using and where is the IRIS set?
I'm using a .8 AT screen 130" 2.35. I have my iris set to -5 but obviously don't get that punchy image even though my whole room is covered by black velvet. Today, I ordered SAT 4K which is supposed to be a 1.18 gain.
Prometheus is not available in 4K/UHD (yet)
It's a 1080p Bluray upconverted in the Panasonic Player to 4K
12' Throw to a 120" 16:9 1.3 gain screen, remote powered drop down I bought on ebay 8 years ago for $250 shipped
My viewing distance is ~ 9' eyes to screen
JVC X750 in Low Lamp mode with zombie10k's settings, Iris clamped down -10, Auto 2
Lots more pics (4K and 1080) in my build thread
