Shohreh didn’t have a single lead role in a movie or TV show beforehand. She wasn’t even B list at the time of Expanse despite a long successful career. Karl Urban is B. He had Dread 15 years earlier where his face was covered. Trek was supporting. Thor was a minor role.
The A, B, unknown tiers have nothing to do with the actors ability but their current popularity to get viewers to watch what they are in.
The Expanse had Shohreh. The Boys had Karl Urban.
I would consider both of them to be A list even before those two shows.
