No. These are limitations in other convertors which try to translate
macros. TeX4ht produces a DVI file which it then tries to convert into
some HTML format. Parts of this translation are changes in character
encoding (the DVI could be based on a 7-bit font encoding like OT1 and
ë being presented as ¨ and e) and graphics file type. As DVI supports
for the dvips convertor only PS based images TeX4ht looks for PS and
EPS files, which are converted to PNG format for the (X)HTML output.
Part of the translation is also a loss of text flow around floats
(wrapfig, picinpar, and such), it all becomes sequential. And
sometimes the fonts used are exchanged because TeX4ht has its own font
Certainly there are many options I never discovered.

I'm sure calibre's command line tools offer a bit more control, though
I'm also sure that the new look will be quite different.

The pdfscreen package could be useful. It allows for example to set up
different "paper" sizes, a small one for screen = ePub and another one
for print use. But it also adds navigation elements... (which can be
customised – and also omitted?)
From error to error, one discovers the entire truth.
