Precisely. I'd be very happy to have a ProDisplay. I may even buy it for the aesthetics (well, above and beyond everything else - I'm also a professional photographer). But as you say, it's more the attitude. I'm guessing whatever proprietary stuff they've done to drive the XDR at 6K in HDR isn't compatible with DSC, and there's little interest in fixing it.

XDR uses DSC on any RDNA (5X00) card, it’s not proprietary.

Which makes me wonder even more why DSC is completely non-functional for any other monitor under Big Sur and Monterey.
