To get any device with a screen with an USB C port to function as a monitor attached to a host with an adequate(!) USB C to USB C cable somehow the pixels need to get from the host generating them to the panel of the device. Either they travel as a video signal or instead they travel as data in a proprietary format where an application on the host generates this data stream and the other half of the application on the device copies the pixels out of the data stream to the display. The former .. doesn't exist? In older tablets people were like "hey, look, a HDMI port, why does this not work as a monitor?" and now they are like "hey, look, a USB C port, why does this not work as a monitor?". Even the otherwise very notable upcoming Dasung notEreader (eInk ereader, Android tablet, mini field monitor) doesn't present itself as a USB C monitor to the world, it sports a HDMI port for this purpose. Anyways, Duet does the latter over USB already, with the Lightning port carrying the USB signals. if it doesn't work with USB C I would expect they will fix it soon if the iPad Pro provides the necessary capabilities. iOS is a very closed system so who knows what's going on there. Duet would need to instruct the USB C port to become an Upstream Facing Port and if Apple doesn't provide a mechanism for this then you are SOL.
