Apple watch face while charging

When I put my 4th generation Apple Watch on its charger, it has a screen that shows time, date, a red dot, and a green circle showing how charged it is. When it goes dark, I can touch it and get back that screen. This is not the screen I have when I wear it (although it is close to my night-time screen).

My wife's 9th generation Apple Watch shows her Mickey Mouse default screen on her charger. That isn't nearly as useful, as she has to do some work to determine how charged it is.

Where did my charging screen come from? Can we change my wife's charging screen to that one?
