What gamma are you using for HDR content? I tested so far a 3D LUT DCI-P3 with power gamma 2.2-2.4 with nice results. Now I tried a 3D LUT with madvr set to output in HDR format and ST2048 and JVC also on ST2048 and Guardians of the Galaxy looked fantastic. But when I looked at Iron Man 1 it was not watchable with it. Might be caused by just recalculating the 3D LUt instead of creating a new one with the JVC on ST2048 and HDR profile.

I was thinking I should go for:
1. A 3DLUT for 709 content with a gamma 2.2 or a bit higher using JVC 2020 profile since the calibration was made in DCI-P3
2. A 3DLUT for DCI-P3/BT2020 with gamma ST2048 using JVC HDR profile (which it would switch to automattically on my 7900)

Does this makes sense?
