22 year veteran of CGI here. It's not less work. It's certainly different work. In fact it probably takes more time because directors think (and studios let them) do do-over after do-over. But once a giant set is blown up, that's it. Once you've flooded the set and soaked your actors it's prohibitive to do it again.
