Buy a phone, don't check if it has any tint, and don't check what panel you get. Just use it and save the time for the more important things in life. I guarantee your brain won't care after a couple weeks. Regardless of how you try to justify it, there is very rarely a defect in all these phones that everyone's going through, it's a side effect of these OLED panels, and the ones that truly are "a unicorn" are almost impossible to find for everyone. I also guarantee you're now tuned to finding the issues, so you'll never be happy.
All the sentiments about people finding the "perfect panel" are all subjective, you can't base comments in this thread on reality.
Someone made a really great point earlier about how if you buy a TV, you'll be allowed one or two exchanges maximum before the retailer denies you, and the panels on OLED TV's are way more likely to have off axis tints and dead pixels etc.
BTW saying this as someone who went through the lottery a million times previously, and settled with the first phone I got this year. I empathise, and I'm just trying to convey the reality after getting out of the cycle.
EDIT: For further reference, the phone that I was happy with after a stupid amount of exchanges for my 15 Pro, looks like absolute **** now compared to whatever my 17 Pro is. Green tint like crazy, and I never saw it till now. There will be no win, your brain will adapt.
