VRR works really well already - some Nvidia users might lose extra functionality like Reflex Ultra that, when paired with VRR, can smartly adjust the frame rate cap. But VRR itself works.
HDR is a difficult beast though... It's hard even on Windows, and very problematic on Linux (though with Gamescope, KDE Plasma and Wayland you can kinda use it already).
I've been using HDR on Linux since February or March and it works pretty well. MPV works great (with vk_hdr_layer), and games work if you run them in Gamescope, which has its own complications but overall it's pretty good.
I still get persistent black screen issues going in and out of VRR mode... It's not as bad on displayport, really bad on hdmi.
