As near as I can tell, it does not reduce the B&W content to 150 PPI. What is does seem to do is to soften lines in images. So a text line would see little effect while a graphic with multiple thin lines close to each would be softened. And as far as I tell when I was testing this, it only applies to kepub files with epub files not showing any effect from this setting. The first two images are from an epub file, the next two are from a kepub. I selected that test image since it was about the worst (a 692 x1000 original image with an svg wrapper to take it to close to full screen) case I found in all the images I played with.
