i need an advice

I have a 10 bit video. I am doing a h265 1080 rip with 10 bits too, using the MeGUI program. The problem is that as a result, the colors on the rip turn out to be slightly different - in the original, there is more red, and in the rip the colors tend to slightly towards the greenish-blue hue.
What needs to be written on the command line so that the color profile remains the same? Or how can I see which one is used in the original?

Very few consumer programs properly handle HDR video right now, unfortunately.
