Set monitor colorspace info for mpv when using windows scRGB output?

[Headcrabed]

Is it possible to manually assign color gamut info(or ICC) for mpv when it's set to scRGB output? So that we can get wide-gamut output under ACM and also benefit from mpv's non-clip gamut mapping implementation.

Thanks. Besides I noticed something wrong: If I set icc-profile in mpv config, the log says a totally different gamut data compared with value read from ICC profile inpsector.

MPV log says:

While ICC profile inpsector shows: Rx=0.691429, Ry=0.307600, Gx=0.283602, Gy=0.655782, Bx=0.151304, By=0.070790, Wx=0.308758, Wy=0.322311.

Is this a bug or something?

I don't know.

I asked gemini to chromatically adapt it back to D65, as ICC profile manager shows it chromatically adapated to whatever chad says, D50 by the ICCv4 standard, it wrote some python code and executed it https://share.google/aimode/Mnj6xaVURTrudfc8k

There seems to be a difference in Gy only. Likely some rounding with chad matrix in the .icc file

Rx = 0.689326, Ry = 0.306990

Gx = 0.263426, Gy = 0.664897

Bx = 0.146564, By = 0.063754
