Default Confusion

All Blu Rays (highest quality of any source) ship with Chroma 4:2:0 Chroma subsampling, so nothing is "degraded" over the HDMI 2.0 spec itself.

HDCP 2.2 also specifies 4K/60 with a 4:4:4 color space, and that is part of the HDMI 2.0 spec. However, you won't see native 4:4:4 content even in UHD, because the chips do a fine job of decompressing 4:2:0 content without degradation of color loss. HDMI 2.0 specifies 18 GB/s bandwidth and that is more than enough for even 7k content.

Maybe, plus some confusion as well. Info was from AnAndTech:
http://www.anandtech.com/show/9152/f...-hdcp-and-hevc

4:2:0 is a color compressed video signal that does indeed cause degradation. Looks like HDMI 2.0 can support 4:4:4 as an option.

HDMI 2.0a extends color to 10 bit, 12 bit and HDR - anyways read the AnAndTech article maybe that will be clearer then my confusion aspect of what is going to happen. I just can't see new UHD Blu-Ray players not supporting all those HDMI 2.0 UHDTV's that has been sold in the last several years.
