Just picked up a store demo with almost 2600 hours on it. The colors are cold, even on D55 temp setting, lamp on "high" and the picture is dim--much dimmer than my InFocus IN82 with over 2000 hours on that lamp on "low". I'm driving it with DCI 4K HDR footage that I shot with a cinema production camera. I have all HDMI 4K 60P 4:4:4:4-rated cables, purchased just for this installation. I notice that the iris controls do nothing. Looking at the lens from the side while it's on, the aperture looks nearly closed--only about 3/8" diameter opening where the light comes through. Is the iris malfunctioning? I spent the entire week reading the manual I downloaded from Sony, and the entire evening trying to figure out why the picture is so dim. Also, I updated the firmware this morning, but I still can't get BT.2020 on the Color Space menu. I am disappointed, as the picture has no more "pop" or color gamut than my decade old IN82. The image doesn't have the sharpness of 4K, despite doing the panel alignment and carefully focusing the lens. It's still soft. Almost acceptable at the center, but soft a couple of feet from the center. Other than the lens shift, and the wider zoom range, my wife and I think there's no advantage.
