I know it sounds stupid but on my ipad mini retina on ios 7.1 all icons look a bit rounded, specific ios 7 but when I am inside of an app and that I press the homebutton, the icon of that app is shaped like ios 6 and it takes less than a fraction of a second to change from ios 6 shape to ios 7. You can try with the new itunes festival app, if you are inside of this app and than go to home screen, the corners of the app have some black lines that make the icon ios 6 like. I know it s hard to understand and has no point but I thought it s good to point out. ---------- I somehow managed to take a screenshoot during the animation from inside the app to homescreen. Second picture is normal.
