I don't know details how latex fragments are translated into SVG but
there is good tool for this: dvisvgm. It is provided by TeX Live though
it works only on DVI files.

Well, the error message is misleading.
If you go via imagemagick, I guess, the image is rendered and converted
to pixel graphics and then converted back to svg with embedded pixel
graphics, which will inflate the output.
The way to go is to customize org-babel-latex-htlatex to "htlatex".
Then, the block without the :imagemagick header argument should produce
a decent svg.
For reference, this works for me (having org-babel-latex-htlatex set to
"htlatex")
