NVIDIA RTX series 10 bit over HDMI supported?

Gday, I plan to get a RTX 3000 series as I read that it support 10 bit over HDMI. I will use it with my LG CX TV which supports 10 bit. Can anyone proof that it works? Also on all models 3060, 3070 and 3080? I want to have a full 10 bit workflow.

Thanks
