Actually, when Blake tossed Yang Gambrol Shroud, and they used it to swing Yang around, you could see a little trail of fire coming from her hair, but it's a very, very short shot. Also, the coloring changes a bit when she hits the mech for the final time, just like how everything became gray and red when Yang was in her "supercharged" mode in the Yellow Trailer when going after Junior. So, yeah, she did use some pyrokinesis, but very, very briefly. I think it only ignites when she's incredibly worn-down, angry, or anxious, based on what we've seen of her using it so far.
