Thanks, that's helpful. I see now that his last part of that post *WAS* with respect to HDR output (not SDR).
CLAW, based on what you've seen with normal HDR output to your JVC with the 1229B Public Beta firmware, do you have reason to believe the 203 is clipping blacks for normal, HDR output -- i.e., with HDR Auto or HDR On set? From your write up, it sounds like you were just doing the normal adjustments in the JVC to establish its HDR picture mode and BT2020 profile.
With my LG E6, I've certainly seen no indications there's anything improper going out for black levels with normal UHD/HDR+BT2020 output from the 203.
Using the HDR Standard picture mode in the LG E6, and with all video processing disabled, I found I had to lower Contrast substantially (from the default 100 down to 87) since otherwise the panel was way too bright for comfortable viewing in a darkened room. And in compensation I also raised Brightness a couple steps (from default 50 to 52) -- but that's nothing out of the ordinary for EITHER of those settings compared to what I'm finding works for calibration of normal, non-HDR content.
The Picture Adjustments in the 203 itself are all left at the Factory Default (0) values.
