Both Houdini and Substance tools are basically programming for artists. Unreal Engine Blueprints is visual data-flow programming. So to answer your question: yes. The question isn't as much do you get higher pay for this, it's more about you can't even do most of the high tier CG work without knowing this style of programming. Zbrush may be one of the last things where you can just sculpt things, but even that can get really technical really quickly.
