The degree to which the differential indicates a problem depends on how high the State Of Charge is. The differentials tend to increase as the SOC gets lower. Just off the top of my head, if it reads 100 or more with a full charge, that would concern me. 150 when full, and I'd be looking for ways to trigger Turtle mode, to get a warranty replacement.
