MacBook Pro Retina Image Retention LG SJA1

As stated in the title, my MBPr has severe image retention. I have owned it since late December of 2012. I am going to take it in to Apple but am afraid that they are going to replace it with a screen (Samsung or LG SJA2) that is not correctly calibrated for my logic board giving it a yellow tint that cannot be corrected through calibration. Has anyone been sucessful in getting Apple to replace their entire MBPr? Additionally, my screen and keyboard backlighting make a buzzing noise when the the brightness is turned down. I have also noticed that the default Color LCD profile for my current LG display has the model code A00F (A00F is LG and A00E is Samsung) in the .icc name which makes me believe that the default color profiles differ between Samsung and LG displays (picture
