I tried it, immutable is not for me on the desktop, went back to arch. Bazzite had HDR working on the desktop with my nvidia card, ended up doing the same in arch after finding out it there was a flag I needed to set, personally haven't had an issue with that set.

If you're good with immutable though, it seemed decent enough to me, was little to no fussing to get things going. I don't really distrohop though, historically I use debian on my machines but arch has been a solid experience in the past month.
