Tiny spots all over the screen - m2 MacBook Air 2022

Some foreign stuff on the screen may not easily come off with a cloth. Gently use your fingernail to see if one of the spots will break up.

When cleaning the Display I personally like to place the laptop with the back of the Display on a smooth flat surface with the Keyboard & palmrest up in the air (reverse of how you use the laptop). This way you can easily wipe the display without it moving or risking the display twisting. Just make sure to spray the microfiber cloth with the LCD cleaner and not the Display itself or you may cause liquid damage to the display or the rest of the laptop.

You can take the laptop to Apple or an Apple Authorized Service Provider to examine the laptop.

It is most likely either spots of dirt or spots of the anti-reflective coating coming off. I have seen some people report having bubbles appearing on the glass of some of the latest Silicon Macs from 2022. Definitely cannot tell from a picture. Usually display issues can only be determined by a first hand examination of the device itself.
