Unfortunately at this moment in time, I believe this to be true. Most buyers of art just want art on their walls for decoration. Meaning they don’t really care, who the artist is and why the artist does the work of art. Art from my experience is only purchased by the rich and/or educated buyer. Digital art is slowly changing art. Like music today, free copied music is ubiquitous. But people still go to live concerts. Images of many artist may be obtained free from the internet. But, quality printed images of artwork are still bought at land based galleries.
