Trying to launch a basic default Unity app in the headset only renders an entirely black display. I can interact with the the app when I launch to VR from editor, but not when I create an actual "Universal Windows Platform" project. I tried launch another app on my device (HoloTour), and I also get a black screen. I noticed an issue listed on here: https://developer.microsoft.com/en-us/windows/mixed-reality/immersive_headset_support#graphics_card but I am using a desktop with a GTX 970. Everything works as expected (both HoloTour and the default Unity app launch as expected) on my other PC which has a GTX 1080.
