In Samsung Themes, there are 4 options: Wallpapers, Themes, Icons, AODs. These can be seen at the bottom bar of Samsung Themes. If you are loading a wallpaper, it will only include settings for the lock screen and home screen, therefore, when a wallpaper is applied it prompts the user to choose whether they want it applied to the lock screen, home screen, or both. You can select AOD themes by going into Samsung themes, and selecting "AODs" at the bottom bar, or searching for a theme, pressing search and selecting "AODS" under the search bar. The themes option specifically will include settings for all (lock screen, home screen and AOD). This is why when you apply a theme, a "Apply content?" pop-up will appear informing you that the Always On Display will be modified and ask if the user still wants to continue.
