My turn to laugh. This has also been posted many times.Here’s a gal that actually analyzed the display. She points out similarities to Samsung displays where Apple sourced these
Let me try to simplify this one more time for you.
At launch, each year, there is a percentage of iPhone screens that are exactly like they should be - neutal white point, good brightness, good contrast.
Each year, there is also a group of iPhones that have defective screens - yellow film, low contrast, low brightness, and in the case of oled extreme color shift off axis.
For the sake of discussion, lets say the split is 50/50. So 50% good screens, and 50% bad screens. That means, when you buy a phone, you have a 50% chance of getting a good screen.
At launch, and especially this year, that rate seems to be more like 30/70, so 70% bad screens, 30% good screens.
But that 30 does exist. Meaning there is a batch of correct, non-yellow phones.
People are returning their yellow phones to re-buy and get a swing at the bat to get a good phone.
Any analysis of a phone only applies to that exact phone, not all 12s. Meaning this girls video only proves that HER PHONE was yellow.
There are in fact non yellow perfect phones. Just like every year. You can indeed get a phone that matches last year's screen tint.
I hope that helps. I literally can't simplify this any more for you. I even put a nice baseball reference in there for you. Trying to help out my man.
