How to automatically dim iPhone and iPad wallpaper when dark mode is on.

If you are a fan of iPhone's Dark Mode and Night Shift then you obviously care about your iPhone's appearance in dark settings, and probably don't want to see a really bright wallpaper. iOS 13 has a setting that will automatically dim your iPhone's wallpaper when Dark Mode is on. To use it, head to Settings -> Wallpaper and toggle on Dark Appearance Dims Wallpaper.
