> Is "422" "ok, I admit it's formatted correctly, but I can't process it for some higher-level reason than syntax"?

That is my understanding. Something to say that the request is understood as an HTTP request (therefore not 400) but the server doesn't know what to do with it, usually in the context of a POST, or it's otherwise invalid for processing.
