Theme Approval Process

How does Envato test quality of a submitted theme?

Do they manually enter data without reading the documentation (test for intuitiveness in setup)?
Do they manually enter data by following theme documentation?
Do they import sample data provided by author and following theme documentation?

Obviously, if they just look at an author’s provided demo url, everything looks prettier. I’m just asking so I would know if the ugly part of my theme is the already fully setup (with all the data) theme or the part where there is only a few data. Obviously, a wordpress site with less data looks incomplete and ugly.

Thanks in advance.
