That's probably a high estimate. There is quite a bit remaining around the edges, but it is a significant amount of the land mass. I don't think you could store that amount of terrain/structure information in around 250MB.

Have you compared to the map generating website for that seed? Just looking I'd say you've unveiled maybe 1/3 of the surface max. It's still a lot of area.
