What color and audio formats does Mass Effect LE render in?

What color space does Mass Effect Legendary Edition render in? What about for SDR vs HDR?

What standard would capture it? HDR10, HDR10+, DolbyVision?

What color bit depth? 8-bit? 10? 12?

What audio bit-depth? 16, 24, 32?

Trying to screen record for a LP that I'm going to be doing some very aggressive color grading on so I want to capture it right. 

Windows 11, Nvidia RTX 3070

OBS v.29.1.3

I'm thinking about recording either in rec2100 PQ or Rec2100 HLG

Thanks!
