I can only get my 820 to output 4k60 4:2:0 to my JVC X790R due to either HDMI cable length (30ft), or the wall plate connection, which is right in the middle of the 2 cables. The cables are BJC belden FE bonded pair. When I run a short hdmi cable directly from the 820 to the JVC I can set it to 4:4:4 FYI. Am I losing anything by (only) using 4:2:0 10 bit? Should I try anything else? A "certified high speed" wall plate perhaps? I don't really want to replace my existing cables with active ones...
