XPS 15 9560 Color Accuracy

Just received a Dell XPS 15 9560 replacement due to a screen flickering. The replacement has the same issue so literally there is no difference between my original laptop and the replacement except for the display. As seen in the attached picture, one laptop has a warmer color and the other a cooler color with both being at the same color settings. I have to send one laptop back and was wondering if anyone could answer which one is more color accurate out of the two. Thanks in advanced.
