Not at all. I'm sorry that you took it that way. I am simply saying that none of this matters if you don't just pick up a camera and film. Six months ago it was "is there really that much difference between 8-bit and 10-bit" and now it's "is there really that much difference between 10-bit 4:2:2 and 10-bit 4:2:0?" Being inquisitive is good! But from my perspective it really does look like you're worrying about things that, in the big picture, won't really impact what you'll be using the camera for, especially if you're just an enthusiast or hobbyist.
Regardless, none of us can really answer some of your questions because it boils down to preference and what is acceptable to you. If you can't notice the difference between the two then does it really matter? Does it matter that I can? I don't think so.
