I'll just say, in my opinion, Joker takes on a character study about a mentally ill man to show the callousness of soicety. That is very new to CBMs. The fact that is dark and serious is an aspect of the movie, but it is not defined by it.
As for the blatant award campaigning, I mean it was invited to Venice. Phillips did not ask to be invited, they just were. Logan was never even up for discussion, as awesome it was.
Have a good day.
