Exactly. The compression level of DNA is magnitudes better than anything we can even come close to. DNA usually doesn't even contain specific counts (like 5 fingers on hand) or sizes of organs and so on - these are given by the processes that run in parallel and cause the cells to hit spatial / chemical / electrical or other limits. It's like putting lots of house builders on specific places where the house should be and each one would just keep building a wall until the he hits another one. There is no compressed house plan, it's a compressed "engine" that builds the result.

Comparing it to machine code on CD/DVD might make more sense then. Machine code where every line has been hand-optimised by nature's hackers over 500 million years.

And in that context, hundreds of MBs is a heck of a lot of complexity.
