Other that Ghostscript's compression perhaps not being as good, so the
image grows in bytes, does this matter?  The resulting pixels are the
same?

I understand the motivation for PDF was speeding rendering, e.g. no
lexing of PostScript, and remove control flow so the linear description
of the page dominated render time, and not hard to predict, or faulty,
loops.

I often run ps2pdf(1) on PDF files here, e.g. from -Tpdf, as it often
makes them use fewer bytes.
