Yes to all of the above!! Maybe the producers think that "normal" make up is boring and won't come across on the screen as well? The face painting side of it just doesn't appeal, and I don't see the point in it. I'm not going to spend 5 hours painting my face, taking a few photos and then taking it off again. Not relatable.
Dealing with skin tones, textures, spots, scars, sparse eyelashes, wonky eyebrows, wonky lips, asymmetrical features etc is much more "real world" amd would test them more I think. (Says the woman who has no make up skills at all!)
