Somewhere between those numbers. They might have gone for better known actors because the property is such a risk, but Marvel has typically avoided star power in favor of up and coming stars. Think Chris Hemsworth as a typical example. Recently, you've got Brie Larson, Chadwick Boseman, and Benedict Cumberbatch, which are known in certain circles, but not household names. I wouldn't be shocked if Iwan Rheon and Anson Mount were still in a movie if they were making casting decisions. I doubt Ken Leung would be in a movie because he's very firmly a TV actor, but I don't think the replacement would be instantly recognizable either.
