Users don't really care if an element in the game looks more "Apple" but Apple cares. If you make a fun game users will play the game and tell them friends about it. If you incorporate features that Apple wants showcased and graphically build the game to fit in with iOS7 you have a better chance to get featured by Apple which will get your game more visible.

You need to decide which features you are implementing for the user and what you are implementing for the OEM. Also, Apple will care more about your game if you incorporate and Apple iOS feature more than the design and look.
