HDMI 2.0 can do 10 bit 4:2:2 YCbCr and TV support it that one of the rare cases where nvidia is doing 10 bit.
a bd player should use 4:2:0 10 bit for 60 hz HDR that's lossless.
i'm not sure where this 12 bit comes from because PC don't really support it. you could do it with 16 bit and let the driver do the rest but still.
