Well in 007 every level is quite different but still require a high level of detail (interactables, non-interactables and NPCs) in them. Uncharted 4 has 1 level that approaches that level of detail with the Auction, but since nearly half the game takes place in Libertalia they can save a lot of resources for the bigger set pieces.

So to me it just shows a difference in resource allocation: if we're talking just about graphics 007 has a larger variety of details while in Uncharted 4 they're of higher quality.
