I have the adapter from Cable Matters I think and I’m fairly sure it supports VRR at 4:4:4 chroma subsampling. Tested it on a Hisense U8H. I stopped using the adapter though because on Windows it wouldn’t work with VRR, the screen would kind of go black when I moved the mouse. Not sure what it was.
I think the issue was a lot of things being sold in the early days of HDMI 2.1 that claimed full compatibility, but there was so little hardware that actually supported it all that most people had no way of testing. And I suspect all the usual stroke-at-the-keyboard branded Amazon specials just took all the existing HDMI 2.0 kit and stuck new labels on it.

I can confirm on this some time tomorrow
Good to know.
