Friday I got my replacement Pixel 2 XL. This was an accidental damage replacement from Assurant.
The device I received had VERY old September or October 2017 build on the device. I'm not even sure it was shipping code. I looked for the update and when I did I got this message:

The update it took was actually the Sept 5 update. There wasn't anything interesting there, but the device ended up downloading at least one dogfood version of an app: the playstore:

Overall the playstore had a real refreshed look to it. I say had because at some point the device downgraded all of the apps to production versions on its own.
