Well, of course the driver still does the dithering algorithm. However, its
resampling to 720ppi will be a null operation, meaning that it won't create
any additional artifacts. In my view, it's worth explicitly resampling in PS
to 720 or some submultiple only on images that you discover have visible
aliasing or moire, which in my experience is pretty rare.
