How often to change internal screen protector?

I have a 2024 RAZR which I got 5 months back and there was a horizontal line across the screen protector at the place where it folds.

I took it to an in-perwon shop and they replaced the protector for free under the manufacturer warranty.

Can the screen protector damage the actual screen if it folds too much? I just got a little worried when the protector had a horizontal scratch develop across it
