There's only one single thing I feel fairly confident would have been different with Iger at the helm. And that is the baseline intelligence to not publicly admit that you're swindling customers. Or making broad and factually incorrect statements about the age demographics who they're making animated content for. But that's pretty much it. Hell, I don't even believe Iger disagrees with Chapek's aforementioned comments, he just probably has the sense to know not to admit it out loud (or would word it in a less stupid way).
I believe that had Iger remained CEO (which he still effectively was until December 2021), there would have been virtually no difference in the way the parks have been managed, priced etc etc. The price hikes and cuts to the guest experience during Chapek's extremely short reign have been entirely consistent with Iger's business practices. I will be shocked if anything changes in that regard with Iger being put back in control again. If anything, I expect them to get even worse.
I have a pretty equal dislike of both those foods, same way I feel about Iger and Chapek.
