Good idea!
However, the Pixar end logo wasn’t a change made just for home media releases. I once saw eBay caps of a 35mm reels set (someone was asking $10k USD for, ridiculous you say) and one of the sellers pics had a shot from the Wall-E variant and then the MPAA G rating card. I also recall another eBay CA listing for a Spanish localized/dubbed 35mm print and that had the Pixar variant along with a scratchy BVI up front.
It sounds like the films director originally wanted to use this variant since the teaser had it, but some memos were ignored by higher ups and did not make the cut on premiere, but got added to later prints when new filmouts were made.
