Yellow tint on the left side display

Hi there, i wonder is it normal to have a yellowish tint color problem on imac 27inch display, i mean i can clearly see there are different, in terms of the white tones.

on my left hand side it is white, however on the right take out roughly 1/3 of the screen are white yellowish.

I just replace the display like days ago due to grey smudge and now yellowish 😟, at first at the store i start to notice a slight different in color tones, i did not make any noise cause i thought this is a brand new display and 2nd reason is my eye playing tricks on me (Been driving long distante whole day). but after short while using it, i start to realise it is not my eye! haha...

will apple care still cover it? i mean i just change this new display with apple care.

this is really fustrating i need to use my comp very often yet if i send it in it take a week or so to get it done..grrrr

Looking towards anyone reply regarding about this issue thank you.
