I hope you don’t think this is “just a bit”
On that 3rd one if you look at the left elbow it might be misleading because of the camera angle, but look at how far back the right elbow is pointing.
I’ve seen one girl us a “elbows pointed up” pull, but it is the exception and would require 1) exceptional shoulder mobility and health (you are loading the shoulder in an severely internally rotated position, not a great idea) and 2) have a the perfect body proportions to snatch with a perfectly upright posture (so that the bar doesn’t need to be as far back in the catch position… long torso, short legs with longer tibias than femurs, and short arms.
As with everything don’t focus on what “some” are doing. Focus on what "most’ are doing.
