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 massive 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).
