However, it appears that the default background image for Catalina’s login screen is /System/Library/Desktop Pictures/Catalina.heic In previous versions of macOS, I believe it was possible to change the background image of the login screen by replacing the default in /Library/Desktop Pictures/. Note: This question is about the background image for the login screen (what you see before you log in), not the desktop wallpaper, which can still be changed by going to: System Preferences » Desktop & Screen Saver » Desktop.
