It supports DNLA (in addition to airplay) which as far as I understand is the subset of uPbP that matters in this case.

DLNA is a 3 parts architecture in which the CP-800 is the renderer, one still needs the server and the controller parts and the application you mention is not DLNA controller, it's just an application that connects to the CP-800 to control some settings completely outside of the DLNA scope. There are many DLNA controller applications available, like Media:connect for IOS, and many others for other types of devices.
