I got a 6+ two days ago, it has a very nice even cool display just a gorgeous screen ,compared to my brother's which has a yellowish warm display. However I just notice a black dot at the center of the screen what seems like dead pixel!!! I don't know if I should exchange it and play lottery I don't want to get a yellowish or uneven screen. Should I just go to the Apple Store and ask them if they can fix the pixel??? Would they be able to fix it with out replacing the phone?? Any advise would be appreciated thank you guys.
