I don't believe this to be true. I think the difference is graphic designers tend to use much more of their toolings' functions, whereas almost every day I'm surprised someone I work with doesn't even know some IDE feature was possible, let alone how to use it. Hell, almost every frontend developer I've ever seen use either VSCode or WebStorm orchestrates everything from the built-in terminal and is baffled when they never see me use one - because it's all configured via run configurations, and that's a _basic_ feature.
