Yeah. When I refreshed from an 11 to a 15 Pro… the only noticeable difference was the better camera.

It's a remarkably good camera for a phone. But I agree. I went from the 2020 SE to the 15 Pro and it was kind of whatever. Well, the screen's higher refresh rate is nice to look at too. That isn't really new to phones in general so much as it is to iPhones, though.
