yet it looks like this. reference normal at the bottom

I’ve also had others with HDR screens test this and its universal, so it’s not my screen or screen setup.

This also looks like this on a microsoft Series X devkit. HDR worked fine before when I was in an earlier version of unity and/or gamma colorspace

i am reading posts on here that say somewhere along the line HDR display output from built-in was removed as a feature?

Is that actually what happened?
