Is the logo on the back of the iPhone 5S a mirror like on the iPhone 4S? I have my iPhone 4S, and the logo on the back is like a mirror. (I like it because if I get an eyelash stuck in my eye, I can use it to look into my eye up close and get it out.) Is the logo on the back of the (silver) iPhone 5S a mirror as well?
As you can see in this video : Yes it's the case on all 3 models. 

With the iPhone 5, it's was only the case with the white model.
