HDR for sure no ... Thy just implementing full support HDMI 2.0 and mostly for next gen Gemini Lake. I don't think if that even work before on Linux. On Windows working HDR?

The Kaby lake and Apollo lake can play 4K 10bit HDR file, the only issue the metadata in HDR file is outputting.

Could you show me this metadata, that is ignored? Or are you talking about the missing 10 or 16 bit precision visuals?
