Lots of misinformation here. Is it because Fury X doesn't have native HDMI 2.0 support?
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.
