I have already returned 2 8 Pluses for uneven tints. One was red at the bottom, yellow at the top on white screens. The other red on the left and right sides and yellow in the middle.
Do you get used to it? Will I eventually just forget about it or will it bug me for as long as I have the phone?
I did not notice anything like this on my 6 Plus.
I'll give you my take on it. I've gone through 5 iPhone 7s and returned all of them due to these display issues. I then went around looking at display models in stores whenever I could and found 95% of them had these issues as well. I have only found one or two absolutely perfect displays.
I then recently got a iPhone 8. I thought it was a perfect display until I found something with it. The bottom is warmer. Most iPhone 8s I've seen have these issues. I found a absolutely perfect iPhone 8+ on display yesterday but it literally had visible dust under the screen.
I am not sure about getting used to these but then I really want to. Both my parents have a iPhone 7 and both have uneven tints and they just don't notice it. I pointed it out to them and they just couldn't tell.
I’ve gotten plenty of perfect screens-in fact, that’s all I’ll settle for for. I wouldn’t keep it. Most units don’t have these issues with screen inconsistencies.
You can try this if you are interested in seeing it :
1. Turn off true tone. EDIT : Actually works with true tone on too.
2. Open safari. Open google.com
3. Rotate phone to the left so the earpiece speaker is on the left and charging port on the right.
4. Compare the grey areas marked in the screenshot on your screen. They are slightly different for me. The left side is slightly bluish grey vs the yellowish grey at the edge near the home button. Its a subtle difference as if the bottom half of the screen is slightly warmer.

If you think this is because of transparency, you may try it with gboard or swiftkey because they have white themes with no transparency.
I personally think it may have to do with the screen being top lit. I tried this on mine, dads and mom's iphone. All are same.
