Wait a second... it looks like there's transparency involved in the

In Inkscape it will render on the white (transparent) background, but,
the PNG would just have transparency w/o that "artificial" white. I
guess the quick test is to make the background opaque in the document
properties and test exporting to PNG again.
That was it. After making the background opaque the exported bitmap
displayed exactly the same in IrfanView as the original in Inkscape.
