Yeah exactly, the overlay is just a visualization in the viewport, a visual representation of the mask, not the functionality itself. And in a very Blender kinda way, it gives you lots of control on how you want your settings. Because maybe you don’t like how the model looks with a mask, so you can tone it down for your visual satisfaction. Now that I say that, I wonder if you can change the color of how the mask looks? Could be buried somewhere in the infinite sea of options.
