Differentiating between main and guest cast on that show is "icky" too, I guess, as they just lump everyone together in the intro. Some of those are clearly minor 1 episode roles, tho. And the main characters seem to have gotten promotional photos, while the minor roles haven't.
Considering that it's a parallel worlds story, with the potential two copies of each character, you can't be sure who is minor and who is not after watching just one episode. Promotional photos are also shouldn't be relied on, sometimes only the bigger stars of the show get involved in promo shooting.
Maybe things will get clearer in the following episodes, sometimes a credits in the pilot are made different from the rest of a season.
