PE+ is the first ROM to have system phone dialer obey dark system theme. I also found a setting to make contacts app have dark theme; the setting is within contacts app (see screenshot). However, I could not find a way to make Messages app have dark theme.
Edit - Went to PlayStore, updated Messages, and found dark mode in 3-dots menu (it may have been there before update?)
