When nothing is changing, you do not have to touch the GPU. Yes, without Panel Self Refresh there would be this many bits going to the panel at that rate, but the display engine would keep resubmitting the same buffer. No need to rerender when there's no damage. (And when there is, you don't have to rerender the whole screen, only the combined damage of the previous and current frames.)
