Just testet. Looks like you are wrong.
Live boost clearly makes the objects my EVF better visible when it's dark and the frame rate set to high. (E-M1, Firmware 1.1)

That is because Live View Boost fixes Live View to one exposure preview that is independent of the exposure you set. When you use higher exposure compensation with high refresh rate Live View gets brighter, too. So for exposures where live preview is wrong anyway it can make sense to activate Live View Boost to get a brighter (or darker in bright light) view.

With the E-M5 Live View Boost fixed preview to the equivalent of +-0 EV, with the E-M1 it seems to be different, maybe even dynamic in that it uses a higher value for dark scenes.
