Apple's $5000+ Pro Display XDR uses DSC when you plug stuff into the rear USB ports, so I think it would be fine to use it on the Studio Display also.

Even without anything plugged in, or any other displays downstream of the host thunderbolt port, XDR will preferentially negotiate one HBR2+DSC stream if the host supports it. (17.28gbps)

Which yes, means that a hypothetical 6k120 could be done at the same compression level as current 6k60 by using both HBR2 streams that a Thunderbolt 4 host port is required to support.

Hey, would you have some details/info on how I can figure out what exactly my XDR is ‘doing’ (find its connection type like you explained, and pixel depth that the graphics card is outputting - 8 bit vs 10 bit).

I have the M1 Max 14”, and also bought the XDR around a month ago for the extra 6k screen real estate. One thing I noticed is that I can’t figure out what pixel depth it’s running at on my M1 (intel shows 30 bit framebuffer in System Report, M1 shows nothing). SwitchResX software is reporting that it’s running in “Millions of Colors” (8 bit), but I’m not sure if that’s true. The same setup is reporting Billions of Colors on an intel MacBook.

It overall seems to be there’s things missing for the XDR <-> M1 interactions :S
