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+)

I just mean 4k h265 that has HDR and one that does not have HDR but is still 4k etc..

Ah - you specified 10-bit non-HDR originally. I thought your question was particularly about 10-bit SDR content - which is pretty rare. I don't have access to 10-bit UHD SDR content to master from - so that's why I discussed 1080p SDR 10-bit which I mastered myself.

What sources of UHD h.265 SDR content do you have that you're interested in playing? In my experience pretty much all UHD h.265 stuff is HDR, though there are some Netflix series that are early UHD SDR that Netflix stream in h.265.

Most UHD SDR stuff, outside of OTT streaming, still seems to be h.264 (and 8-bit, as 10-bit h.264 is a niche format) - though I do have some early UHD DVB-T2 h.265 off-air test stuff that is SDR 8-bit.
