STEPS TO REPRODUCE
1. Have night light on.
2. Wait for some time until reentering night light settings. (Unknown by how much - 10 minutes? 10 hours? Until geolocation changed a bit?) 
2. Reenter night light settings
3. Exit night light settings (e.g. switch to a different item in the navigation)

OBSERVED RESULT
Prompt that asks about unsaved changes is shown when exiting the night color screen.

Prompt is only shown when the user made changes.
