My problem with the Hierro comparison is that while Hierro was always on and gave no visual indication of being present aside from maybe sparks when a sword struck skin, Blut Vene has to be activated and has a very clear visual representation, namely the black veins along the user's defended area. Kubo clearly remembers that part of the ability, since he included and made a big deal out of it with Blut Vene Anhaben.

Agreed it don't fit 100% but then again those lines are small and how many up close shots of Quincies beening hit did we see?

That or it was just implyed that they were using Blut arterie.
