I believe you when you state that the model is incomplete.
Nevertheless, anyone who is surprised that the iv file would be
significantly smaller than the original DXF file hasn't spent much
time looking at how grossly inefficient the DXF format is. :)

On the basis of that, I feel hesitant to ask what DXF primitives are
in use by this file, since you'd have to dissect them a good deal in
order to see. It's entirely plausible that dxftoiv doesn't support one
of the many ways DXF has for declaring a surface.
