So do you not really lose any DR by going to 50? According to that chart, you don't. Or do you lose something else?

In the case of the D800 the sensor is configured in exactly the same way at ISO 50 as ISO 100. The photo is just exposed one stop higher. That means that the highlights are clipped one stop earlier (lose one stop of DR), while the shadows are raised one stop (gain one stop of DR).
