If you are referring to photos & videos from our documentation – the way we get the black background is by turning off the Photo/Video (PV) Camera so only the holograms are captured. I do this by unticking the PV checkbox in the Windows Device Portal for the HoloLens under Mixed Reality Capture. Screenshot attached.
Let me know if this helps or if there’s something else you are referring to.
