iPhone What does this button do, when setting wallpaper?

Can’t figure it out

It controls Still vs Perspective (wallpaper moves as you tilt your phone)

Can’t figure it out

i thought the same thing, that it controls perspective/still, but instead actually i think it maximizes the graphic you have chosen as wallpaper or leaves it the same relative dimensions which in some cases might mean its not covering all 4 sides of the display.

ah, the previous method with text/buttons was easier to understand.
