HDR to SDR : Bad color

[Atillart]

Hello, I have a recent film in both HDR and SDR formats.

I want to convert the HDR to SDR, aiming for a result similar to the SDR version.

I'm using Rigaya Nvenc to convert HDR to SDR.

I've tried all the available algorithms, and the result is always a greener image than the SDR version.

I don't know if there's a setting to slightly shift the colorimetry so that it leans more towards blue than green?

Saturation can be manipulated, in edition to color space, color range, pixel format,
SDR->HDR, SDR-> HLG, and color lookup tables [LUTs].
