Given two files, a compressed file which must be uncompressed to play, and an uncompressed one which does not require extra processing - why would the game ever bother uncompressing te compressed file when the same data is already available uncompressed?
With hard disks, I could see reading the compressed version from disk and decompressing giving you the bytes faster than reading the uncompressed version. With SSDs that advantage likely went away.
Because with lossless compression you can save a lot of storage space without losing any quality. You are thinking about lossy compression.
I think you misunderstood his question.

There's no true use case for that that I can see.

I would guess to save on installed size?
