Therefore, an LCD is always going to emit more light at any one moment.

This is not true. An EPD screen in its white state reflects a certain percentage of the light striking its surface (the commonly cited figure is 40%), while a standard backlit LCD reflects pretty much nothing. There is no cumulative effect of ambient light and backlight. If there were, such backlit displays would be fantastic in direct sunlight.
