From my experience edges dull because they roll, not wear away. Of course if you are cutting sandpaper or some other substance that could actually remove steel it could be an exception, but in almost all cases rolling or other edge deformation is the cause of dulling. Even in the very rare case where edge wear might occur, edge rolling would would most likely account for the majority of dulling.
As an example, if a knife is sharpened to say, 150, it will be duller after chopping vegetables on a wood cutting board. You can’t sharpen a knife using broccoli or wood because sharpening requires removing (wearing away) steel. In the same way, broccoli or even potatoes won’t wear away the edge. The edge dulls because it rolls.
