anti reflective coating on macbook air m2

i had recently brought this macbook air m2 (not more than 3 months) and my screen's anti reflective coating is removed and i'm not been able to see any thing dark in the screen as i can clearly see the screen is not working as expected. i don't have any accidental warranty but my laptop is well within actual warranty, M'I eligible for the free repair or what should i do. P.s i have done nothing wrong with the screen (no silly experiments).
