Little details noticed in an IMAX 70mm presentation that might not be visible otherwise?

The first time I saw Oppenheimer in 70mm IMAX at the Chinese I was seated close enough to the screen that I noticed Robert Downey, Jr. has a pierced ear and I thought I fleetingly saw another character wearing a Mickey Mouse watch. These are things I definitely wouldn't see on my TV screen and might not even in a non-IMAX DCP presentation.

Do any of you have examples of details that stand out in IMAX but might not otherwise?
