Oreo Colorize is great for super-saturating the Pixel 2 XL screen....

It makes just enough of a difference that it makes me feel like it's the vibrant screens of yesteryear.

Had anyone else tried it?

Sounds like a good option. The screen looks great to me at stock settings, but I am coming from a Note 5 Edge so maybe I never got used to supersaturation. I turned on that phone last night to look for an app I was using and that screen looked much duller than stock Pixel XL2.
