Just got mine set up, Apple put on a screen protector too. No Apple leather case in stock but I got a nice Belkin one clear back and bottom back/side is black, very nice looking. 256GB Product Red. I upgraded from a 6S regular size and trust me this phone is huge compared to that.
Did you get the case from the Apple store too? I'm curious what I'll find as far as cases when I go in later today. (I've seen what's online--maybe there's more in person?)
