Here's my take:
My phone history is iPhone 4 -> Samsung s5 -> iPhone 6 -> Samsung s7 Edge -> iPhone 6 (my s7e smashed after about the 20th drop in two months, slippery bugger!)
I was seriously excited about the new Pixels, even watched the live event (which is common to lots of you I'm sure, but not me!). I was a bit disappointed to see the Pixel 2 still had the huge bezels, so decided to go for the XL2 and pre-ordered one that night. Got very very excited, went to look at one on display in the shop and loved the look, then read all the original reviews which were fantastic. Then the screen problems started being reported. After reading every article I could, and getting more and more worried I started coming on to these forums, which made me even more worried!
Last night I ordered a Pixel 2, thinking that I could play around for it for 2 weeks and, if I liked it, cancel the XL2 as I was just too worried about the screen. But today, I went back to the shop and spent a lot of time playing with the XL2 with different brightness settings, vivid mode on/off and different colour backgrounds. And do you know what...
The screen was absolutely fine! Seriously could not see what the issue is. Yes, there was a faint blue tint when viewing off angle, but I would never have realised it if I wasn't looking for it and there's no way it would bother me when using it. Coming from the iPhone 6, the colours didn't seem dull whatsoever, but I'm sure that will be different for those coming from a Samsung phone. I did everything I could to try and see burn in, but there was nothing, and this is a phone that's had the display on all day for over a week. Same for graininess.
No doubt there's too many bad quality screens around, but as long as you get a fully functional one then you will be totally fine, beautiful in fact (And if you don't get a fully functional one, send it back until you do!).
In other words, I've cancelled the order for the smaller Pixel and now I'm back to being excited for my XL 2 to arrive!!
