I am also having the same crescent shape in my iphone 6 gold front facing camera, hope Apple should replace it for all the devices having same problem.
Apple has apparently stated that even though it may not be affecting the performance, they are still doing unit replacements. If the Apple rep you speak to balks at replacing it, explain that the reason you want the replacement is to avoid it becoming worse in the future, and if it becomes worse only after your warranty has expired but you reported the problem prior to the warranty expiring, then that makes a lot more work for everyone involved.
If they still balk, ask for a manager or Senior Advisor.
