But look at, for example, "Days To Go". I think it's a very typical iOS 7 design, and it meddles the content with the UI: the caption looks exactly the same as the actual content.
On iOS 6, you knew what was the "window frame" (UI) and what was the "window" (content), and you could look through the frame without any cognitive effort. Now both parts look the same.
What I meant is this: On iOS 1-6, the UI is very clearly UI. The rectangle between navigation bars, tab bars and status bars is the content. It's like looking at a snowy landscape through a heavy, wooden frame.
On iOS 7, everything blends together and I don't see how this puts the focus on the content. E.g. in mail, the scrollable content has almost the same colour as the bars above and below it. How is it more prominent now?
