I have another question, which video decoder should I use for best HDR playback?
If I select CUVID the playback on a demo HDR video (sony camping demo) is extremely choppy
If I select DXVA (copy - back) it's starts a bit choppy but evens it out eventually
If I select DXVA Native it plays ok, but the colors look inverted or something and overblown (see image below)

And in none of the selected decoders I get the HDR popup my LG tv gives when HDR content is played.

you wont be able to play HDR on your PC as nothing is sending any meta data to your TV, videos will just play as normal video. DSPLAYER cant play 4k HEVC stuff either, so if you are playing 4k HEVC demos this is why its choppy.

if you want smooth playback you'll have to use KODI krypton but you'll lose LAV FILTERS so you have to play 3D frame packed stuff on an external player. I am currently experimenting with how best to deal with my own media needs. I have a fully 4K setup with a 65 inch 4K OLED TV, i'm having all manner of problems with KODI, DPI and graphics drivers. My advice - sack 4k and HDR off for a couple of years until all the issues have been resolved, by that time there should be loads of content to see.

I'm currently using kodi krypton with MPC+MVR+LAVfilters for 3D playback, however i'm toying with the idea of just playing 4k stuff in krypton and having all my 1080p stuff running on MPC-HC as an external player. So many options here, none of them ideal, this is why we really really really really really need a DEV to build DSPLAYER on Kodi Krypton, then we'll be back to being able to play everything on one player and not have to use exteral players.

DSPlayer should be able to play 4K HEVC. LAV Video can do the decoding.

have you tried it? cost it dont work for me.
