I went to my local corporate Verizon store and immediately found the very prominent Pixel 2 display. They had a Google Home speaker playing music pretty loud, and it actually sounded pretty good. I found that to be pretty impressive, but I digress.
I found the larger of the 2 phones and started playing with it. I was messing with it for a good 5 minutes before I realized it was an OG Pixel XL, not a Pixel 2 XL. In my defense, I've never held a Pixel of any sort before today.
I asked the CSR if they had any of the 2XLs, he said they did in the back. It turns out that this particular store couldn't get the XLs to charge through their security dongles.
Once he brought out the Pixel 2 XL I was able to inspect it, and I did in fact see the blue tint. I strongly disagree with those who say it appears at "the slightest angle". I would estimate that the tint didn't change until I brought the display to at least 15 degrees off normal. Would the blue tint bother me? Not even a little. When I'm looking at my phone I look straight at it. Would it bother some? Well, obviously it does.
In my mind, the display is in fact behaving as a polarized display would, and I believe that the circular polarizer is what's causing this phenomenon. Of course, if this bothers you it probably won't matter what is causing the issue, but that's what it appears to be to me.
So the bottom line is, if this bothers you you'll have to rethink your purchase of an XL. I personally don't think it will bother most people.
Apart from the change in tint, the display looked fabulous to me. It was bright, crisp, sharp, the colors nicely defined, not over saturated. Close to perfect in my estimation.
I didn't have any issues with the feel of the coating on the aluminum back, the entire phone felt plenty premium to me, though it's not really a fair test since all of the various cables and security dongles were still attached. I loved the feel and the look of this phone.
The front facing speakers sounded great. They won't replace my home speakers anytime soon, but they sounded great for speakers in a phone.
My experience did not make me want to cancel my pre-order for even for a femtosecond. If anything I'm more eager than ever to get my phone in my hands.
If the blue tint is going to be an issue for you then you may want to go see a phone in person.
