Don't hold your breadth. Sony after the last layoff is slow to respond.
I do believe you are a little confused about what is being discussed here. 2.2 means HDCP 2.2. That means the receiver will act as a HDCP 2.2 relayer. It will pass HDCP 2.2 as well as all earlier HDCP versions. Sony 4K content is protected by HDCP 2.2 and the display must be HDCP 2.2 compliant protected and all things in the video chain must be able to relay or send HDCP 2.2 if the source material at 4K is protected by HDCP 2.2.
HDMI is something else. Its is a method of transmission and it is bandwidth limited. HDMI 2.0 technically has a bandwidth of 18 GBS. HDMI chips need to accept 18 GBS to be fully HDMI 2.0 compliant. We nerds around here, but no one else,stuck up techies like us have our own idiotic labeling to save posting bandwidth.. We call chips with 18 GBS bandwidth HDMI 2.0 A. Most stuff out there because of chip unavailability use chips with only 10.2 GBS bandwidth. This can be remembered because it rhymes with Tippecanoe and Tyler Too. Our UK friend, Manni01 is sloppy. He cites 10.0 GBS when as a video nerd he should say 10.2. But he is English and can be forgiven for not knowing this old political slogan. We call these 10,2 chips HDMI 2.0 B. This bandwidth is used on say the Sony 4K projectors and because of the limited bandwidth will as far as 4K or UHD signals are concerned only pass 60 fps info at 8 bits with only chroma subsampling at 4:2:0.
This is deemed as low quality by us and pretty much all video nerds in the free or other worlds. We want more, say 10, 12, or 16 bits at a minimum of 4:2:2 subsampling. At 24 or 30 fps there is enough band width to up the bits and subsampling to make us happier than pigs taking a mud bath. We are basically simple nerds.
