Okay, well, toss me into the mix of folks getting a replacement. I thought mine was fine (maybe just a TINY bit of pink blotchiness at the top), but then I let the battery run all the way down and fully charged it today (I like to do that with all my lithium ion batteries at least once). Lo and behold, I now have more pronounced pink blotchiness at the top and some new blueish blotchiness in the center. And, where I could only notice the tiny bit of blotchiness in the dark, now I can notice it in decent lighting.
So, I have a replacement coming on Saturday. Getting the replacement ordered was painless via chat, literally no questions asked. I said I have blotchiness, the rep said they'll send a replacement. My fingers will be crossed.
