While I'm mostly there with you, I feel like it's a bit too strong to call it elitism. It does assume the user has background knowledge and quickness to recognize the difference between an icon, label, and clickable button and some part of these decisions come from some insularity amongst ux designers may be, so it might stem from some out-of-touch-ness but it's probably more unintentional than being elitist.
