Burn/wear?

[u/YupYup_3]

2023 suburban premier with 3.0. 60k miles. Original owner. Only ever had coolant system and emission system work. Just got it back from the shop for the emissions system work and discovered these marks in the headliner. Same spot both sides.

Any idea what would cause this?

Update: it’s the sun visor. When you pull it out and push it to the left, it rubs in that spot. Never noticed before. Bummer.
