White Uniformity Problem on LG C9 55"?

Hi r/OLED

I took delivery of my LG C9 55" yesterday and noticed during an all white scene that my screen has a definite blue tint on the edges of the screen.

Not my image, but this is the closest I can find online that is nearly exactly what I have:

Would you say this warrants a return, or is this normal?

Thanks.
