Don't forget this is a hybrid. The electric motors are also the generators so the hv battery can feed the 12v system.
At highway speeds the electric motors are just along for the ride and power is coming primarily from the engine. Even if the electric motors are providing motive power, that power is also coming from the engine which would mean again, it has to work harder therefore would benefit from numerically higher rear gears.
Edit: would benefit by staying in V4 more often.
I have no doubt we would get similar mpg to what you are if we lived in a warmer climate, had lighter wheels, had the aero improvements, and had 2wd not 4wd. I do love this vehicle though!

Have you cleaned out the HV battery?
the blowers in these HV are pretty much dust collectors
