I should note that the yellow on mine wasn't very easy to see it was incredibly subtle and I could only really see it on very light colours like when viewing this forum. The image I made above to illustrate the problem was very exaggerated to make it easier for you to see my problem, it was much much fainter than that.
But yeah mine is perfect now. I'd recommend giving Apple a call and actually talking to support and go through what they tell you as it never occurred to me to try an SMC reset and I think had this not worked he was going to ask me to try some more things before organising a replacement.
