Stopped by a different Verizon store today to check out the Pixel 2 models to see if my findings were similar to what I saw the other day. What I found was interesting. The colors were, as before, quite subdued in comparison to what I'm used to. The colors on the OG Pixel, Note 8, and LG V30 at the store today were all more saturated than what I saw on the Pixel 2 models. But here's where things get interesting: the colors on the Pixel 2, both the regular AND XL variants, were the same (save for a slightly warmer temperature on the smaller model). The screen on the smaller Pixel 2 is made by Samsung and the screen on the 2 XL is made by LG, yet they looked similar. What does this mean?
To echo was
@Lava Lamp Freak has been saying, as well as what The Verge said in their review today, the "washed out" colors we are seeing are the result of the Pixel displays being sRGB calibrated. This is good for the fact that the colors you are seeing are in fact the TRUE colors that the app developers, web designers, etc., intend for you to see. Now, whether or not you prefer that is a different story. I prefer the saturated colors, but I digress. I'm probably just too used to my Nexus 6P's display.
Something else of note -- I activated developer mode on the 2 XL and went into the developer options and couldn't find an sRGB toggle, unlike what I have seen on my Nexus. I searched for "sRGB" in the settings app (via the little magnifying glass near the top of the screen) and actually saw the sRGB option listed, but upon tapping the option I was brought to the developer options screen which, again, did not list sRGB. This further enforces the theory that sRGB must be on by default, and the option to disable it is hidden.
Very interesting decision by Google. While I understand their reasoning behind this, I again will say that your average Joe is going to look at other smartphones and then look at the Pixel and think "this display isn't good." Maybe a software update will add the option for even more vivid colors (since "Vivid colors" under the display settings on the Pixel 2's didn't seem to do much).
Moving on from the screen, a few tidbits: I really like the design of the regular 2 as well as the 2 XL. They are darn good looking phones, and I personally really dig the "Kinda Blue" color on the smaller device. The finish on the back of the devices feel great. Having owned metal phones for years now, I'm tired of the cold aluminum feeling when picking up my devices. The finish on the Pixel 2 devices are welcome changes. The Pixel 2 XL in particular feels very light -- I didn't realize how heavy my Nexus 6P was until holding the 2 XL. Also a welcome change.
Just some more investigative work for anyone curious (as I was). Cheers.
