It wasn’t the first time Disney/Pixar did small changes mid-theatrical run. Toy Story 2 as you may know had a very tight production schedule from nearly losing most of the original files and the Pixar team scrambling to finish it all just a month before release. The first run 35mm prints of Toy Story 2 from Nov 19th 1999 only had standard credits and not the intended “bloopers” ones, which were added to all later US prints and some of the foreign dubbed/localized ones.
And as for the alternate “globe” footage during Buzz’s speech, that was definitely first seen on the foreign dubbed/localized 35mm prints, some of which only had the standard end credits retranslated, and made it’s way to the PAL DVDs. The UK/AUS and foreign subbed 35mm prints still used the 2nd US version, since those were often refurbished 35mm US prints with a ratings card/BVI reel badly spliced on and the MPAA cards often hacked out.
Monsters Inc. was also basically the same situation as TS2, standard end credits on the premiere theatrical run and bloopers credits on the later/foreign ones. However, Monsters had two versions with differently framed shots, VFX and object rendering (the “piss” snow cone being a notable example), the Nov 2001 theatrical version and the December 2001 “company ending” version. The Nov 2001 theatrical version, the basis of many widescreen and HD/4k versions, has a few shots that are differently composed and framed along with others having different/unfinished renders of objects and standard ending credits. The December 2001 “company end” version, also seen on most VHS and 4x3 DVD versions, has several shots that are reframed and recomped with different renders for objects and backgrounds, in addition to a new end credits that has bloopers and cast doing the musical number “Put That Thing Back Where It Came From or So Help Me”.
In addition, it’s foreign dubbed/localized version on 35mm and some PAL DVDs also have alternate shots not on the English versions, with some characters doing only gestures instead of lines to reduce rerendering lip sync.
