Nah man, Bloodmoon took place hundreds of years before Dragonborn, so some changes could very easily be made.

With cities I guess, not really ancient dungeons though.

We see people building Apocrypha looking temples when Miraak enslaved them.

That only happens recently. The whole reason the Dragonborn DLC starts is because Miraak finally discovered a way to effect the outside world from Apocrypha. I doubt anyone really knew how to do this before him.

With a Apocrypha themes prize at the end, the Black Book, why can't we see Apocrypha architecture within that certain place?

For the same reason the Ohgma Infinium isn't surrounded by Apocrypha architecture, or Volendrung isn't surrounded by Dwemer architecture.

The Black Books are artifacts, they were found and brought to these ancient nordic/dwemer holdings. Unlike "Dragon Shout walls" which were literally built into these areas.

I am really sad to see no Morrowind stuff aside from RavenRock.

In Bethesda's defense, Solstheim was originally supposed to add more of a Nordic feeling to TES: III.

(and don't forget Tel Mithryn)
