Scuffed/dented my brand new iPhone 7

Hi all, I just picked up an iPhone 7 and within the first day of owning it, I dropped it and scratched the back and dented the side of the phone. I also scuffed the surroundings of the camera. I'm usually pretty careful with my devices and always use a case, but my case had not arrived and I should've waited before using my phone naked.

Fortunately, the phone is still 100% functional and working perfectly. The camera lens didn't crack and the screen is still pristine (as I dropped it on the sides and back). I want to know if Apple can replace the entire rear housing of my phone, and I'm obviously willing to pay the full amount for the repair as it is my own fault. I just don't want to get a replacement unit as I've had some horrible experiences with refurbished units. I also want to avoid 3rd party repair shops so I can keep my warranty. Attached below is (part) of the damage. So is a repair by Apple possible guys? Thanks in advance.
