Hi, I'm playing around with creating an HDR to SDR 3dlut from a previous calibration. I followed the instructions further back in this thread, and selected source colour space BT2020, tone curve SMPTE 2084 (roll off) and entered the display peak luminance as measured. I changed black output offset to 100% as I don't want a BT1886 type curve, I want the same curve as my SDR 3dlut (REC 709 2.4). Using this profile everything seems too bright and washed out, like it is a BT1886 type curve which I don't want. If I switch to MadVR's own HDR to SDR conversion with my display peak luminance set there, things look much more like I'd expect. Am I doing something wrong? If I open up advanced options in Displaycal, you can select 'source colourspace', but there is also a 'content colour space' which was defaulted to DCI P3. What's the difference between content colour space and source colour space? Should I be changing content colour space to REC 2020?
