Hello Tom

A pleasure to have a librarian lol, well already the previous versions 
of LibreOffice converted to Ms Office format are necessarily more 
dancing in size as you have noticed, I will advise you to publish the 
latest version of LibreOffice 7.0.1.2

then to come back to your question I don't have a screenshot but I send 
you mine which also shows a document at the base ods of 33.6 kiB 
converted to xlsx format of 26.9 kiB but when you look at the content 
level the xlsx version is in excel zip so compressed at the base where 
the xlsx size will be smaller than the ods version in size because it is 
compressed at the source.

I hope to have answered your concern if not please specify your question 
to me with screenshots so that I understand well why it is not a 
question.

cordially
Sandra LOUVEZO
