They have everything scanned (in their library) in 4K, though no more than 30% of the material is in a HD "Restoration", from Thad K to me on FB.
His database for these mediocre HD remasters did not include the Figaro cartoons, so I am curious how they'll look. That said, this is a pass for me.
As per the B&W question, I don't think many of them. Maybe a dozen at best?
