We would expect to see an improvement in Cell to Pack Ratio vs Cell Capacity. That means that as the cell get larger so the use of the pack volume becomes more efficient.
As expected the transport battery data from the pack database shows this relationship. However, the upper pareto frontier for the data shows that you can still design a competitive pack with a small capacity cell.
