Yes, but with multiple compression technology available. I use RealVNC where there is only one knob for controlling image quality, but in TightVNC for example there's a choice of using zlib, RRE, hextile and its very own Tight encoding[1]. The problem with Qt over X is that it tries to send every frame on every redraw event. With VNC this is automatically limited by the frame rate.
