Macbook M1 screen

Hi there,

I've bought an M1 macbook air (about a month ago) and I noticed that stains started appearing on the screen. They closely resemble those seen in the "screen gate" back in 2014-2015. I've been very careful while handling the device and even though the stains are quite small they seem to be slowly growing in number and size. Did anyone notice something similar ? What should I do ?

Thanks in advance.
