Has anyone spent time playing with the AI Wallpapers on the new Pixel? Thoughts?

Maybe I missed it, but I never really saw it mentioned previously, just stumbled across it while checking out the new wallpapers. For those unaware, the phone will use AI to generate unique wallpaper images in a variety of categories, based on some select criteria you specify. I think it's very cool, but I'm easily impressed by gimmicky things. This is on the 8 Pro, not sure if it's on the regular 8 or is this is an example of the on device AI capabilities they were toting for the Pro?
