Apple repair - will they still do it?

Hello, I have a Macbook Pro (I know this question is listed under MacBook only, I'm sorry) and its going to be repaired soon, and I just remembered apple doesn't do repairs on things that are opened by unlicensed/unauthorized persons.

But I just remembered months ago many months ago I had opened it to clean out the fans fully. Not with a spray can, I was going to unscrew them and what not, but during that process a screw or two got a bit messed up. BUT, not stripped. possibly messed up enough that if they look at it close they might notice. But it should be un screwable.

Would anyone happen to know if they will still do the repair? I don't think its stripped. but still there is a 10% chance it is. (Can't really be certain of everything I guess)

Would they still repair it if the screw was stripped? I am 90-99% sure it is not, I swear. But there's always a level chance it could be, as I am no screw expert.

Thank you for reading!
