Replacement edge has a pink hue

[popkurn611]

I just got my replacement s7 edge in from at&t. My original had black lines running through the screen. I noticed that against white backgrounds, like in a Gmail message or any white space that the white is not bright white it looks like it has a reddish pinkish hue. I put it up to my husband's s7 active to compare the whites and his is pure white...mine is not.

This is a picture compared to my pixel. The pixel whites are a true white while my s7 whites have a pinkish tone . I am pretty sure my old s7 did not look like this. Just curious to know if this is normal
