New ARC-170 75402 Discoloration

Just got this set brand new from Target the other day. Many of the white pieces fresh out of the bags have slight discoloration on them as shown in the picture.

Has anyone else seen this in new sets? Is this a true quality issue that I should contact LEGO about?

You can see in the picture the difference in colors of the various white pieces. Especially the yellowish color in the long 8x3 wedge part.
