Implement HDR Format?

[Jaxx497]

Hey, just a simple feature request to include the HDR format within the Video fields.

An example from a python library returns the following among other instances:
'hdr_format_compatibility': 'HDR10',

Which Python library, specifically?

Although the MKV format has a "Colour" tag for video tracks, it does not appear to be in wide use. But if I can see how a Python library is probing for HDR data, I may be able to do the same.

I've used this library extensively to much success
