That is an interesting difference with the 8088+CGA platform by the way. The Amiga has no problem displaying entire screens of uncompressed data. CGA however is so bandwidth-limited that you simply can't update an entire screen at acceptable framerates, so the lossy compression that is used with XDC is a requirement to improve the framerate to FMV-like levels, it is not primarily required for data reduction on disk.
