An option in madTPG to set the input HDR metadata, similar to how we can set the output metadata, would be cool.
Your text in bold, that's what I meant and thought was implemented from the go since it comes from the same author. Viewing the PQ curve tells the whole story, can't tell how close it actually tracks from SDR luminance curve measures.

HCFR should be supporting this, best would be to ask Zoyd on AVS in the HCFR thread.
I asked, no reply so far. Why do you think 2.4 gamma is recommended, i.e. why does it matter any if we can select the gamma a display is calibrated to in MadVR?
