Slightly dim/dark on sides of screen,

Don’t worry. Look at my Legion 9.

Just compare 😀

How did this happen?
And does it get worse?

This problem was from the factory and I am not the only one with this problem. Please note that I have a MiniLed screen. In your case, the IPS matrix and backlighting are normal. I stopped thinking about it because in real use I will never look at a white screen.

Okay i was a little paranoid 😅

I wouldn't return it because there's always a chance to get a version with a worse screen or with problems not related to the screen at all. Besides, I don't see any problems in your photo. I always pay more attention to "screen bleeding" on a dark background.

Did your problem stayed the same or it got worse?

I do have little screen bleeding

This is due to uneven pressure from the screen frame. The problem does not get worse over time.

Okay

For myself, I realized that the only solution to not encounter this is to buy a laptop with an OLED screen.

And I am very glad that the latest generation of laptops are starting to switch to this type of matrix.
