Tone mapping curve = BT2390
color tweaks for fire & exp. = balanced
high recovery strenght= none

On my projector I've chosen widest gamut and a gamma curve of 2.4.

Now I want to start some calibration testing with LUT to reproduce better my UHD files.

Normally I use LightSpace to generate Luts.

My questions are:
1) I need to create a Lut targeting to rec.2020 or DCIP3 ?
2) The gamma curve of this lut must be BT.2390 or a classic power curve 2.4 ?

thank you so much.
If you are using pixel shaders, the LUT should be SDR and not PQ.

DisplayCAL recommends DCI-P3 and pure power 2.20. You could also try 2.40.
