Pixel 3 XL? Go outside on a moonless night, away from any street or house lights, so you need a flashlight to keep from breaking your neck. Go into night mode in the camera (More, then night mode). Take a few pictures. The camera can see a lot more than you can. (Be prepared to hold still for a few seconds for each shot - lean against something.)
Google is still the camera to measure against - again.
(Of course, with the Verizon version, the bootloader is locked, but I guess you don't want to buy it directly from Google - they have a payment plan too. I'm still paying about $30/month for my 2 - no interest.)
