While I can’t see your photos (I’m using the iMore app) I would consider, were I you, getting one of the many $5-$10 tempered glass protectors on Amazon and going for a flawless install (i.e.,steamy bathroom for 0 dust).
Thats what I did got cheap ones, and still had dust and lint behind protector.. the protector itself if perfect but edges don’t settle anymore because I lifted it to get the remaining dust/lint behind the protector and top left edge messed up a bit cause I lifted it like 4 times from there.
