JRVR Feature request - Native colorspace playback option
karmat63:
"P3 limited in 2020", sounds like the perfect solution.
Waiting for it... thanks.
Hendrik:
I added these for a future build:
NEW: Added "DCI-P3-D65 in BT.2020" as a screen gamut configuration to JRVR.
NEW: JRVR can optionally process the gamut after applying a 3DLUT.
NEW: When performing HDR to HDR tone mapping, the gamut can be reduced to DCI-P3 in BT.2020.
Note that when applying a 3DLUT, I would not actually recommend to use the "DCI-P3-D65 in BT.2020" for your Screen Gamut setting, but rather just stick with plain BT.2020, as the 3DLUT may output colors ever so slightly outside of the DCI-P3 spectrum to match your screens behavior, and you don't want JRVR to change those again.

Fantastic Option! This now means that for those of us with HDR displays that hit (around) P3, JRVR will map that 10% of HDR UHD BD's mastered above P3 down to P3 prior to hitting the displays (poor) gamut mapping! The added benefit is that over time as displays continue to expand past P3 (some are now already P3 +15%) we can just change a setting in JRVR to full 2020 (or P3 "enhanced" or whaterer they call the next step up in colour space)! Love it.

I imagine that the screen gamut configuration won't be disabled anymore, using 3Dlut.
Fantastic option, for me (a maybe for many others) the last bit to leave MadVR behind. The actual implementation of 3Dlut HDR to SDR tonemapping is somewhat bugged in JRVR, as there is no option to report to display to use DCI-P3 inside BT.2020, and so a smaller gamut is inflated inside a much bigger one, with obvious oversaturation, expecially on skin tones (I've seen some have reported this problem, eventually related to color gamut mismatch).
Many many thanks.

OK - Split out the discussion on Inverse Tonemapping for SDR ---> HDR conversion https://yabb.jriver.com/interact/index.php/topic,136136.0.html
