Really sad this is a bare bones release. I would love to see in-depth background into the production of the film. From the opening computer graphics, model work and animation as well as early production design.
Regarding picture quality I saw a digital version of the film and the matte lines are completely absent making me think they cleaned up the film. Doesn't sound like the case here. Maybe there's two versions, one cleaned up for digital streaming, the other more faithful to the original film as seen in the theaters.
'Note that the "absence" of the film's overture is causing quite the stir with fans; apparently Disney has included the overture on the disc but it's essentially inaccessible without running some end-arounds.'
