About the closed preview: it is a simulation, cropped from the exact composed wallpaper shown in the open frame beside it. Your Duo takes the one wallpaper you set and reframes that same artwork when the phone is closed — there is no second file. The exact region shown when closed can be positioned in the phone’s wallpaper editor, so your closed view may crop slightly differently from this preview.
