iPhones of the same model being different from one another
I recently had a replacement device after that my previous iPhone 11 Pro Max had been water-damaged.
Two months down the lane of my 90 days warranty; I got a chance to compare my iPhone with a friend of mine and turns out, my screen display looked a bit yellowish despite having all of the default settings turned on. This concern made me have a comparison with the same model iPhone in the local market and yet with a comparison with 3 more devices, my device still looked different (yellowish) while others were all bright blue.
So, I went to my Apple Authorized Service Provider who gave me this replacement device and I have been told by the Apple representative (at Future tech) that if they were to line up iPhones of the same model then all of them would look different from one another in terms of display- so how much truth is in it?
I am concerned because @applesupport on twitter told me that all of the displays are same irrespective of their different region.
My mind is all boggled- The yellowish tint is very bothersome to my eyes and has significantly lowered my device’s resale value.
Can somebody assist me in this regards as to what to do?!
