Strictly speaking, it's a moot point. Snapshots and diffs are easily convertable to one another, which allows to present either way no matter the underlying structure.
We can talk though about how the data is actually represented in storage. Here efficiency comes forward, and good compression algorithms will detect a small change for a big dataset. But that's not necessarily what would be present to the user - though it could be.
