Endgame was no longer in any film conversation by the Autumn of 2019. Ford v Ferrari is a different beast for a different market. The same goes for the other 8 Oscar best picture nominees.
I don't hear any cinema expert talking about how MCU has left a massive footprint. Half of the best picture nominees already have resentment for Endgame. Little want to bring up MCU anymore in any conversation about cinema. Endgame's loss was the Oscars sending a message that they agree to that. Something that has destroyed the reputation and perception of comic movies should not be seen as a successor to Star Wars. Star Wars did not damage its own genre, MCU did.
The legacy we have is to make less Endgame movies and more Jokers to win Oscars. This is not a massive footprint, Its a small footnote, and I am not a massive Joker fan.
