I don't think so. The surface area of large bubbles will add up to a lot, and small bubbles will have many times as much surface area. Even if there is more surface area at the top of the tank the bubbles are passing through the water column very quickly, creating a lot more interaction between bubbles and water that can be oxygenated.
In my opinion the interaction between bubbles and the water column create more oxygenation than the flow of water across the surface of the tank created by the bubbles.
