I can guarantee you that the only part of that film that was scanned for anything and printed from the digital copy was the part where they added tink and the fireworks. It is extremely expensive (and slow) to scan and laser record film at IMAX resolution. There is nothing about the Soarin' film that would need digital editing tools. It's just a bunch of simple scene changes. I'm sure they did everything they could conventionally (cutting the negative and splicing it together) and only used digital where they absolutely needed it (to add in digital effects).
If they have to print a replacement film, it's not something they can just go do even if they had it stored digitally. There are only a few labs worldwide that do it (especially for 70mm film). Same for making a new print off the negative. There are only a few labs that handle 70mm film.
