Describe the Bug

HDR streaming to HDR clients now produces an extremely dark image on the client that is not really usable after the recent Plasma 6.2 update that has come to Fedora over the past few days.

Expected Behavior

A normal HDR picture without black crush present.

Additional Context

I'm able to at least work around the issue by not streaming in HDR, so it's not showstopping. I have tested this on a Sep 30th build and the most recent lizardbyte/beta copr build that doesn't segfault (the version listed below).
