Usually a Wayland compositor just do very few things like compose different program windows to your display output and feed the focused window input events. Desktop elements like wallpaper, panel/dock etc are considered part of "desktop shell". Gnome have mutter as compositor and gnome-shell as shell (although they are same process). KDE has Kwin as compositor and plasma-shell as desktop shell.
