I could be wrong, but I believe in Disneyland's version, the safari party was more blatantly stereotypical (similar to the Trader Sam situation, where DL's was definitely a... well, let's say a much more dated interpretation of the character). And since modern Disney loves splitting costs between resorts whenever it can, WDW's scene gets the change, as well.
As I said, I think it looks solid. The new characters are still in a heightened Marc Davis style, and -- as of now -- the narration has not significantly changed. If a first-time guest were to ride past the scene, they wouldn't have any indication it hadn't always been like that.
