With my Samsung JS8500 and GTX 1050 I receive 4k 60Hz 4:4:4 8-bit, 4:2:2 10/12-bit and 4:2:0 10/12/16-bit. This is using NVIDIA 375.70 and Windows 10 pro x64. 
 
You cannot do 4k 60Hz 4:4:4 10-bit because the HDMI spec does not have enough bandwidth. 
 
Also make sure that your TV is set to UHD deep color. I have my color setting on ycbcr422 10-bit, but you can use RGB.

I'm not sure why you'd use compressed color format instead of RBG. While you won't notice in games, the desktop, especially text, is objectively worse. Windows Desktop is natively 8 bit so using 10 bit gains you nothing. I've never seen a 16 bit per channel setting.

RGB doesn't support 10 bit color over HDMI 2.0 at 4K. so HDR won't look as good, hence using Chroma instead.

I have a separate HTPC for just Movies/TV using Kodi.

Okay,  but for the vast majority in typical use, 8 bit RGB full would be the correct setting.

I'm perfectly well aware of that.  And well aware that neither HDTV being discussed here natively supports HDR they use a compatibility mode..  ON THE DESKTOP, for the vast majority of use, RGB FULL 8 BIT is the correct setting.

Actually the Samsung JS8500 does support HDR. 
 
But yes on my LG 34in Ultrawide I use RGB. 

As does the KS8000 that I've got coming in. It's a murky world out there for HDR so far.... companies are flaunting HDR on TVs that should not be rated as HDR.
 
I'm hoping Samsung will release a One Connect box with DP 1.3 or higher. I've emailed them requesting as much, because DP will eliminate the need for using Chroma compression.
