List of 70mm films on Bluray?

[Pirate King]

I have a couple of questions, because I do not fully understand. I do know the difference between 70mm and 35mm and the advantages of 70mm. However, here is my questions...

Sleeping Beauty, was filmed in 35mm but there were 70mm prints... How does that affect the PQ?

Also, films like Becket, (Filmed in 35mm) also had what they call 70mm blow up prints..

And yes yes yes, lets have a Blu of Its a Mad Mad Mad Mad World, the complete 192 min original version.
