The light novel makes it almost explicit that she has a true form. The anime doesn't show it off as well, but here's what happens when Dominion Authority uses Holy Smite and "damages" Ainz in the light novel:

 "It felt like the world was distorting, with her at the center of it. A wave of invisible, dreadful power which twisted the world in its wake swept out from her like a storm.

   Something seemed to be crawling under that black armor, like there was an enormous entity that was about to break through the plate and reveal itself. "

This implies that Albedo does have a true form and that it's likely enormous and bulky. The Nalfeshnee hypothesis is actually sounding pretty damn probable given all the hints: the demon looks kinda like a gorilla/boar, has black feathery wings, and is depicted with an imp and a succubus on an official illustration (Albedo has levels in imp and succubus).
