I have been pursuing this issue since a long time and now I'm fed up of trying. Apple recently replaced my screen on my retina macbook pro 2014 13inch. The previous screen was A018 which was superb with bright colors and everything and it was so bright that at full brightness it would hurt my eye, the screen was perfect until the an apple authorized service center scratched because of that I was forced to change the display. Today I went to the Apple Authorized Service Center and they had changed the display with a A020 which I think is the one with the yellow tint and retention problems. I was right as the display was so dull even at max brightness it felt so dull and washed out and it had a yellow tint too. I did not accept the computer and told them that they must provide me with a A018 or otherwise I wont accept it. I just got off the phone with a senior apple rep and he told me apple stopped making the A018 displays so I'm stuck with this, they told me they will try calibrating it so it becomes more brighter and the yellow tint goes away but how can calibration make it brighter? I'm so frustrated that I have to pay the price with a dull display just because a very dear apple authorized service center scratched my screen, shall I accept the A020 which is dull and less bright compared to the A018 or shall I keep pursuing them? ( I have been pursuing Apple since a month speaking with the senior team everyday for minimum 30 mins this is by far they have the worse customer service and I don't think Ill ever purchase another apple product) Your input will be really helpful as this is this is my last attempt And anyone with a A020 and A018 screen please share as to how your screen is?
