Since production companies never release the IMAX DCPs of their screeners to like BD/DVD printers, I'd guess it would be pretty hard to find outside a leak from their own offices (IIRC DCP drives sent to theaters are encrypted ROMs).
For other examples I'm pretty sure The Dark Night and Dark Night Rises had 1:1.43 scenes in it. I feel like Blade Runner 2049 should've been IMAX if it wasn't haha. Not sure if it had the budget though.
