how well does this device play 4k h265 10 bit no HDR and HDR etc when android tv is the OS
and running kodi on it?

When you say 4K h265 no HDR - do you mean playing back SDR 10-bit files, or HDR 10-bit files but output to an SDR display with tone mapping ?

I've had zero issues playing 10-bit SDR h.265 1080p files (mastered myself from 10-bit AVCi100 4:2:2 1080i sources) on my N2 (I don't have an N2+)
