I'm not asking about how to pirate anything, I have for years removed my iTunes purchased files DRM for Archive purposes (same as everyone does w/ DVD, BD, UHD etc). Recently iTunes has added on some files HDR 10 Compatible Meta Data.

I'm using TunesKit M4V Converter (still re-encodes the audio but can live w/ that). I appear to lose ALL HDR10 Meta Data on the 1080 files that include this.

Is there anyway I can extra that HDR 10 data and remux it into the DRM free file? Or is there any other solution I am not aware of?

Thanks guys.
