I know, but each time you go to a foldable subreddit, you can almost certainly find people showing their broken screens. The numbers are just for folding in perfect conditions. It is the weak part, still. No hard glass cover, hardly water resistant, weak dust resistance, etc. I accidentally once folded my screen with a key inside (as I was folding at the same time as sliding into the pocket that had a key in it) and only noticed few minutes later. Survived, but that would not be a worry at all with non-foldable.
