Yes, most swords produced during the war were mass produced and of inferior quality compared to traditionally made swords. However, there were a few traditional swords carried (most often by very high ranking officers) that were family heirlooms.

To the point though, I'm sure that even the mass produced blades had lacquered saya; but, finding out what kind of lacquer could prove difficult. In any case, the lacquer itself was probably of inferior quality too.
