Interestingly, operators are required to store phone conversations, but nowhere does it say in what quality? What’s to stop them from compressing them so much that they take up very little space and are barely, but discernibly, intelligible? After all, they do make mandatory inscriptions on advertisements in tiny letters, and somehow everyone copes with that.
Or consider internet traffic. Some of it cannot be decrypted at all. If something can’t be decrypted, why not compress it to (hypothetically) three bytes? Either way, a data retrieval request will only show binary garbage.
