HDMI settings don't work anymore at config.txt. The new approach is something like that:
The hdmi output varies on rgb 8bit to rgb 12bit depending on the media file (1080p sdr, 4k hdr etc).
I also have a amlogic box with coreelec, and is always displaying YCbCr 4:4:4, that is better?
No. As composition (e.g. combining subs or OSD items) happens in RGB space, there is no benefit in picture quality converting back to YCbCr before driving over hdmi.
For 10-bit output at 4Kp60, it is necessary to output YCbCr 4:2:2, so we switch to that automatically.

Thanks my friend. But when I play 4k remux, the libreleec outputs rgb. thats normal?
Check mediainfo of your remux and see what it says.

As I said
QuoteFor 10-bit output at 4Kp60, it is necessary to output YCbCr 4:2:2, so we switch to that automatically.
At resolutions or refresh rates below that we will output the RGB directly.
