Are different milk drinks really a thing with superautos?

Hey everyone,

I've been wondering about super-automatic espresso machines in general. Specifically, can these machines actually distinguish between two drinks like a latte and a flat white? From what I understand, the primary difference between various milk-based drinks is the amount of steamed milk used. If that's the case, does pressing the latte or flat white button on a super-automatic machine simply change the amount of milk, making these machines more about marketing than actual functionality?

Thanks!
