Well yes and no.....
The original film was produced in theater format, BUT the film had always been intended to be displayed on a ntsc television via really crappy composite in. Because of this the resolution may be higher, but the quality of the frames don't always match it. Basically from what I've seen is the title screen and other interface screens look much better (obviously as they were still art drawings transferred to film) and the main attract sequence looks great, but a lot of the rest of the game looks sub-hd quality, particularly certain rushed sequences. Also like any film transfer a lot of dust and scratches were picked up.
So imho the footage actually looks better at standard def, on a standard tv, because that was how it was intended to be shown. Showing the DL footage in hd is kinda like playing pacman on your new lcd tv... it actually ends up making the game look worse.
