Uh yeah don't listen to hombre there. If you do a warranty replacement and they flag it as physical damage that has nothing to do with the insurance whatsoever and you will be charged the out of warranty fee.
he is 100 percent right ....
To determine if those scratches are "bad" can you feel them with the pad of your finger or if you run your nail across them does your nail fall into the scratch? The warr exchange rep will ask you questions to determine if it's physically dmg'd. Any rep worth their salt if they felt it was dmg'd would encourage you to file an insurance claim.
