It seems that Switcher is copying the background image on each change and stores it in $HOME/.local/share/backgrounds. As I've configured elementary OS to switch team on sunrise/sunset, I have copies for my light and dark wallpapers created daily.
I say that "it seems", because I am not 100% sure that Switcher is doing this. But it looks likely as it's the app that switches the wallpapers.
