Sorry for the confusion, I was using tapatalk not sure why it got a thread title in.
My setup is rs540, oppo 203 with 150" 0.8 gain light grey screen.
I calibrated the below modes:
For SDR: Cinema mode, standard color profile, 6500K, normal gamma, AP at 0, low lamp;
Natural mode all same setting but high lamp;
For HDR: HDR mode, 2020 color profile, 6500K, normal color, AP at 0, high lamp;
User 2 mode all same setting but low lamp.
Now with OPPO set to HDR Off (BT709) , HDR to SDR mode 3 and Target luminance 600 or 300 nits. The below scenes have the top left corner cloud change into yellow ish color for a second then back to normal, this is quite obvious at several similar scenes.
HDR mode has crushed high end so I turned the picture tone back to 0 (was on 7 default) with ST2048 gamma. Tried Dominic's 60_25 gamma also crushing.
Below is the autocal result for the SDR and HDR, the SDR color I run a few time autocal always this result. HDR I don't know how far off as it still give 709 color space for reference?
Here's the HCFR validation of the autocal result for SDR:
