Yes they do, 720/640 = 1.125 so 12.5% more information in the scan line derived from 720 vs 640, weather you can notice this loss depends on the display and content of course. This is counting the information from the black/overscan pixels which I do not think is worth saving. Though it might be nice to keep it if displaying on an SD display so as to not lose active picture area to overscan. I would set overscan areas to full black to increase compressability though and so it wouldn't count as extra information.
