I know Snow White should look that good later this years and there is rumor that there is standard Blu-rays of Peter Pan and Sword and the Stone in the works that might be done in a similar manner.
Here’s hoping.
Sword in the stone is already om D+ in 4K (cropped). If Disney already has it already in 4K, why would it not be the same?
[Edit, sorry missread, you said standard BD. It will most likely be the same]
