I actually think the world building in WF is better frankly. We had nations calling out Wakanda for not doing enough around the world, we had Wakanda dealing with foreign forces and spies and keeping their secrets in check, you actually saw governmental agencies reacting to the world order that Wakanda brought with its reveal.Also, after the amazing world-building they did with Wakanda in the first Black Panther movie, while they didn't exactly drop the ball on it this time, they didn't really add much to it either.
So perhaps its less world-building, than world-connecting. I liked that T'Chala's choice to reveal Wakanda wasn't just a "oh this happened, and we move on" thing. It has real world implications for both the world and Wakanda, some good, some bad. The movie actually gave them more than just quick lip service and I appreciated that, as it happens way too often in MCU movies that are all supposed to be about this connected universe.
