I’m not really convinced that file compression was “mature” at the time. Text compression was reasonable progressed but image compression was created for a reason besides just a requirement for fixed compression ratio.
But I do agree that it was limited in it’s usefulness.

I’m thinking of file compressoin formats like Zip, LHA and ARJ, which would work particularly well if the image was not dithered and used run-length encoding (e.g. the PIC format of the Atari ST). The PNG format still uses the deflate algorithm which is essentially identical to the compression used by PKZip in 1991.
