3DLUT Maker: peak luminance adjustment for HLG

[Sami Boukortt]

Hi,

I see that colormath.py fully implements the system gamma adjustment suggested by Rep. ITU-R BT.2390 based on display peak luminance and ambient luminance, which is great. However, the 3D LUT Maker appears to only expose and use ambient luminance as a parameter (code), which seems like an odd omission. Is it intended, or would it make sense to add peak luminance as well?

Thanks.
