The difference between 4:2:2 and 4:2:0 along with 8-bit vs 10-bit was a hot discussion back when the Panasonic GH5 was announced. It was the first small form factor camera to offer 10-bit 4:2:2 internal, and it confused a lot of people. It still seems to confuse a lot of people, but even if you do understand it, can you even really see a difference between 4:2:2 and 4:2:0?
While only offering 8-bit colour, not 10-bit, Gerald Undone decided to compare 4:2:0 recorded internally on his Sony A7III with external 4:2:2 recorded using the Atomos Ninja V to see if you can really see a difference in the footage. It may not be as significant as you might think.
