Is that this disc rot?

Hello

I purchased used copy of Quarry for Xbox One, however I seen right this moment that it has odd bronze line. The sport nonetheless installs and performs high quality to this point, nevertheless so far as I do know, the discs arent presupposed to appear like this. I did discover hoever that many of the xbox one and X video games have bronze color tint, however that is completly completely different.

I’ve connected two photographs.
