Correct me if I'm wrong, but while Marvel got her powers from the Infinity stone, that doesn't mean she still draws from it. And Wanda they established was always a witch, the Infinity stone merely unlocked her abilities.
Vision is the only one who is actively powered by an infinity stone, and even there there is some confusion over what of him is from the stone, and what is from the vibranium/human mixed body, what is from Ultron, and what is from Jarvis. The new version was activated by what we later found out is Wanda's Chaos magic, so it may be that, since he's powered by chaos magic, there is no noticeable difference in his abilities at all.
