Small crack on the laptop display?

For inexplicable reasons, I got two three tiny cracks on my display from my laptop, which, strangely enough, were created one after the other. The laptop is about 6 months old (HP Notebook - 17-ca1740ng) and I actually take good care of it. I'm also sure that it has not yet fallen to me etc. So I have absolutely no plan how this can happen. But I have cleaned it more often with alcohol wipes like this (it says from the packaging of the wipes that you should not use them for displays), can the surface deteriorate as a result?
I would be very happy to receive answers

Photo?

Is it a tear or a streak?

Oh and there's still a guarantee, so take the dealer's calls and send in the device.

Should the manufacturer take no guarantee (because they say fall).

Removing the display Typing in the number on the sticker costs 60-90 euro.

Installation done.

The whole takes less than 10 minutes.

Instructions for opening on the Internet.

But first take advantage of warranty.
