Hi, is it possible to add a third option for adjusting the 2084 roll-off in DisplayCAL-3DLUT-maker?

The requested new option would be the mean from the old knee point and the alternative.

I’ve successfully exported  two .cube lut files to use in vapoursynth or avisynth for tonemapping, one lut with “adjust roll-off” unchecked and one with “adjust roll-off” checked.

Averaging the two lut gives  a better result, sometimes it’s possible to match the sdr bluray( if it was tonemapped directly from the hdr bluray)
