Generally, I think the Pixel 4 does an excellent job when it comes to white balance, except when it gets it very wrong. Move around the iPhone 11 Pro camera, and the scene’s overall color cast tends to stay mostly consistent. Do the same with the Pixel 4, and its overall white balance can shift drastically, even when you only slightly move the camera. Above, the grid-style screenshot show a series of photos I took in succession under unchanging conditions. I moved the phone subtly as I shot, and you can see the really profound color shift. Again, this primarily happens when shooting under artificial light.
