--- Comment #2 from V Stuart Foote <[email protected]> ---
LibreOffice provides a os/DE responsive Light/Dark color response. And at
25.2.1 Application color themes that also respond to os/DE color scheme (or can
override it). Test with a more current release, or master against 25.8

As to handling PDF conversion to OOXML, LibreOffice uses external poppler
project filter libs to parse PDF objects including text snippets and render
each as ODF drawing objects onto document pages.  The original syntax and
lexical sense of source documents are not encoded into the PDF so those details
*are not present* in the resulting ODF documents LibreOffice produces.

Working with the LibreOffice UI you can combine those imported text snippets
manually and recreate a single Draw text shape holding a sentence or paragraph
of text.  An enhancement requested in bug 32249 seeks to improve such work
flows to heuristically recapture more of the lexical syntax of a document. But
that remains to be achieved.

Filters for Draw (the default), for Writer and for Impress use the same poppler
based parsing filters but each writes out the same draw shape objects to
LibreOffice document canvas.

On filter export to external OOXML format of MS Word .DOCX the draw shape
objects will be written out as draw shapes. Not OOXML text streams and
graphics. So the fidelity to original document or the PDF rendering can be
pretty poor. Even if "round tripped" and opened back into LibreOffice Writer!

Point is, there are better tools that LibreOffice for doing such conversion.
LibreOffice is limited to primarily supporting its native ODF formats. It is
not a PDF editor, nor does it provide an efficient means of conversion to
OOXML.
