I can confirm a slight yellow tint on parts of my screen went away. It's all the talk of pink and green tints I'm skeptical of. Yes, I can see some color shift with angle on mine. I'm wondering if that's all people are referring to. It's very mild and the overall uniformity of the screen is excellent...
Here's a picture of mine. Obviously an iPhone photo of a screen isn't a perfect representation, but you can clearly see how the screen goes from a green tint in one corner, to an almost-white near the center, to about half the screen being totally washed with pink.
It reminds me very much of the color tints you sometimes see on white LED lights that you might find at a hardware store. I wouldn't be surprised if that's exactly what's happening here.
