4K HDR10/DV and Windows 10/nvidia?

ive put together a new htpc with a gtx1060 connected to my new lg b6 oled.

im going to use kodi for video and steam bpm for gaming.

im familiar with setting rgb to limited and full but thats for 8 bit content. does it matter for 4k hdr content which is 10 bit (hdr10)?

outside the scope of kodi, but are pc games full rgb? if so will a setting of

limited in kodi-full in nvidia settings and limited on tv result in crushed blacks on games (but otherwise good video witbin kodi)? if i leave tv to auto for hdmi range would that work or will i have to adjust it manually depending on use?

edit:

does kodi support playing 4k hdr via gtx1060? not that i have anything but demos for 4k, most coming from netflix or amazon apps. youtube hdr maybe? my tv app doesnt support vp9 profile 2 so…
