Samsung Galaxy Clean HDMI Feeds - Specs?

[Mark Am]

I was pretty excited to learn that I could send a clean uncompressed HDMI feed from my Nikon DSLR to OBS that, at a minimum, opens up new possibilities for saving to less compressed files with codecs like HVEC and pro-res. So I started looking at my s22 and see that I'm able to send a clean HDMI feed to OBS. I've looked all over for what kind of feed that might be and the best I can come up with is a short mention in a Filmic video mentioning that HDMI feeds from Samsung Galaxies max at 4k/60fps. Does anyone know if the feed is compressed and what the bit depth is-8-bit? 10-bit?

According to Filmic Samsung Galaxy smartphones transmit compressed HDMI clean data so exporting compressed video may not make much sense if the goal is to create a better file for grading, etc.
