Want to report here. I actually bought the phone from the store 64 GB, black on release day (Friday). It has a scuff near the bottom right seam (that line). I took it to the store yesterday morning and they replaced it with another. I opened the new iPhone's box (sealed) in the store and low-n-behold, it had even worse scuffs. It had a very very visible shinny dot on the power button.
I showed it to the guys in the store and they said they can't replace it for now (they were sold out of course so I was surprised they actually replaced it in the first place), and can only offer to give me my money back. Given the not-many options I have, I took back my original iPhone.
I will use the phone till Apple offers a recall or something. Other than that I think it isn't so bad in my case. I couldn't live with it if it was that replacement though.

That's my phone. 64GB.
