Uneven black strips/Display deviates a little on the screen

[AlcatrazHe]

So I just got my silver Pixel XL 32g from another person, and I noticed that the display under the screen deviates a little bit.
It seems that the left side black strip is slightly thicker than the right side one.
Does anyone have the same issue here? Is it normal to have such "uneven black strips"?

Let's see if this works

doesn't look like an issue to me, likely within manufacturing tolerances.
