Windows 11 Title Bar Inconsistencies

In title bars I noticed a number of inconsistencies. I use dark mode. The setting in Personalization > Colors have both "Show accent color on Start and taskbar" and "Show accent color on title bars and windows borders". Most apps show my selected color in title bars. When I open File Explorer, Settings, Microsoft Store, Notepad, Office, and probably other MS related apps, only the border of the window may show my selected color. A handful of third party apps show the same thing. I know that a few updates ago, MS swapped the positions of the tool bar and address bar and added tabs for File Explorer. I don't know if that messed anything up. Are there different types of title bars?
