I had one of these as a kid: http://www.retroland.com/fisher-price-movie-viewer/ (The one you hold up to your eye).

The cartridges used film. Now I don't believe for a second there was any serious attempts for color accuracy in these things, but I remember the Pinocchio looking like the Laserdisc screenshots do (and not to far from the old DVD).

Being film and not a home video transfer, they might seriously be closer to original intent... I DO know they looked nothing at all like the Diamond BD.

I also had Cinderella, Bambi and Lonesome Ghosts. Now yeah I was a kid, but I have no recollection of them looking significantly different from when I'd watch them in the theater.
