I am writing finally from the computer I regularly use for my classes
-- I did have mupdf, but *not* mupdf-tools. I can confirm impressive
works with my presentation (although the rendering looks a bit less
polished) after installing mupdf-tools.
Ugh -- and the ugly rendering remains even if I install pdftk-java
(that is, it seems that having both installed in the system,
impressive will default to mupdf-tools?); I got back my "nice"
rendering only after purging mupdf-tools.
So:
- with mupdf-tools 1.19.0+ds1-2 and pdftk-java 3.2.2-1:
- Rendering is ugly
- Impressive reports:

WARNING: The input file

could not be analyzed.
The presentation doesn't have any pages, quitting.
I think the result for having both installed should be to default for
the best renderer. If none are available, of course, impressive should
fail -- but the message it conveys is quite cryptic (it does not say
the renderer is not there; in fact, it points at xpdf/poppler. Why
does it fail?)
But more than impressive's message... if either pdftk-java or
mupdf-tools are required for impressive to be useful, they should be
declared as alternative dependencies (defaulting to... well, that's
your criteria 😉).
Thanks!
