But why uncompress it when you're pushing it as a digital purchase on a system that only comes with 32GB of space?

A desire for high audio fidelity? Even compressed, dual-audio would be large. The first game is also not "EAD Magic Compression" and adding in the dual-audio likely tacked on more GBs over the second game.
