Well, in pragmatic terms... Allagans had spaceships, cloning & bio-engineering technology, nanotechnology, sapient AI, and technology that met all their energy needs (post-scarcity in at least one aspect). They're pretty much as high scifi and scifi gets. They're way above what Battlestar Galactica had. Star Trek perhaps a bit closer, but they only touched on transhumanism as an occasional episodic content. Redshirts, once dead, were pretty much... dead. So you can make a case for the Allagans being beyond even that. Perhaps somewhere between Star Trek and Culture, though certainly on a much smaller scale than the latter.

I can't think of any examples that are actually between those 2 off the top of my head, though.
