I doubt the general public is as aware of the nuances as we are here at HTF.No, I think that any movie shot on IMAX cameras - in whole or in part - gets a different line than "Experience It In IMAX".
For instance, posters for "Creed III" and "Quantumania" both say "Filmed For IMAX".
They clearly want to highlight the use of IMAX cameras when that's the case.
"Experience It In IMAX" equals "no IMAX cameras involved".
