Not always, only when SUP (PGS ) are muxed compressed (zlib) in mkv (like is the default). Normally you obtain zlib compressed SUP not supported in other soft.
From BD files (m2ts) work fine because aren't compressed.

BTW eac3to is an abandoned soft and can't be improved for this or other feature request.
With UsEac3toGUI you can extract the SUP decompressed because work like a GUI for MkvExtract like gmkvextract.
