Topic: Do PS4 games played on PS5 play as PS4 Pro versions?

The title of this thread might be confusing but I couldn't think of a better way to frame the question.

Let's take Apex Legends for example, since (as of right now) there is no native PS5 version of the game.

Would the game play as if I were playing it with a PS4 Pro (1440p/60hz)? Or would it play as a base PS4 version? I have a 4K TV capable of 120hz, btw.

@jFug The PS5 would play the PS4 pro version but with less frame rate drops.

Thanks for the response!
