Got curious as well (I use Roam which exports in Markdown and JSON). The files locally are in Markdown but that may be a consequence of importing it from Roam.

Obsidian doesn't seem to have a native exporter as far as I can tell so you have to use a community plugin exporter. As you have hinted at, yes, the exports from Roam and Obsidian generally lose your graph so you only get the plain-text.
