I wouldn’t start the trolling until we know for sure. Early reports from avs are saying the zone output is not 2.1 with customer support saying it won’t come via firmware update:

Sadly, it seems that Yamaha has duped owners regarding Zone out bandwidth with HDMI 2.0 bandwidth, without stating this clearly in advertising. I have not read one single report at the moment that any Zone can pass more than 18 Gbps. If all 10 ports were 40 Gbps, Zones should be able to output 4K/120 10-bit RGB image.
Edit: (from AVS)
"Support called me back this morning and gave me
very bad news.
They told me they checked with Yamaha overseas and that the Zone 2 output
is not 4k 120Hz compatible and that there is no "future update" for it to be ever and they presumed it is a limitation of the board.
This contradicts their website and product literature circa April 2022 that advertises that for the RX-A4A
all 7 inputs and all 3 outputs are "4K120 and 8K60""
It's astonishing how they manipulated the wording in advertisement! I do not trust companies one single inch!
This comes on the top of all fiasco from last 2020 and 2021.
