Disney doesn't believe in restoration. Look at the Fantasia blu ray. They'd rather replace things than fool with working with what they have. Disney does the bare minimum to sell their products. What is so interesting is how they will talk about how great their restoration work is, and they'll show a before and after wipe with boosted color. That shit was impressive 30 years ago, but every kid with a freeware video editing program can boost colors.
It would be so awesome to have Criterion releases of Disney films, but that's unlikely.
