It makes no sense if they just have 10bit tapes for the heck of it, if all material is actually 8bit, and when they are going to show it, they dither it down after it was upsampled once.

Storing in higher precision makes it possible to do overlays, color correction, etcetera without having to add more dither with every single filter. The same reason professional formats are all 4:2:2 even though all delivery formats are 4:2:0.
