FWIW, I ran `/S/L/E/AppleGraphicsControl.kext/Contents/MacOS/AGDCDiagnose -a` on Catalina and Ventura and diffed it.

MacOS Ventura seem to properly sense that monitor supports DSC: "DSC Support: 1, DSC Algorithm revision: 33" , but then simply disables it anyway: "DSC Enable: 0x0".

Interesting. And with maybe a little sense of shame, while I still have those monitors (27GN950-Bs), I actually have a Pro Display XDR on my M2 Studio (and the 2019 Mac Pro before it).

Torn between not wanting to support such behavior, and being one of the minority that could actually justify the Pro Display (photographer who works in at times challenging light environments).
