I checked and it's actually neither. Because this is an older Disney movie, as with all movies back then, it was made for a screen that more resembles the old square TVs. This means it's not a widescreen image and it doesn't need the black bars across the top and bottom on a TV to see the full image. If you have a newer TV that's wide, you'll actually see black bars along the side because the original image isn't wide enough to fill the screen.
