I think of wirepulls as primarily European. That influences me in the fuzzy areas. If it looks "close" but I can tell it's American, I probably don't feel tempted to call it a wirepull. If it looks close to what an American marble would look like but I know it's European, that biases me a little and lets me call it a wirepull anyway.
Since yours look American, I would call them "transparent swirls".
Someone could probably post an example which would test the boundaries of what I just posted but for the moment that's where I am with the term "wirepull".
