Does Charge 4 have a dark screen mode?

Screen is very bright first thing in the morning waking up and checking sleep score. An option to set it up for night hours with a darker screen would be nice. This is also an opportunity for different messages like… these tips will help you go back to sleep in cases of insomnia, or these tips will help get your day started in early morning hours.

You might consider looking at using Sleep Mode.  That does keep the screen dim, along with other things such as preventing certain notifications during night sleep hours.  I don't know your Fitbit model but on most, you can set in Settings, set the hours  to go on and off automatically at certain times on certain days.
