They are both brand new engines. How do you know the MD ISV isn't a modified version of the engine developed for LD use?
I don't. However, I'd hazard a guess that they are actually the same basic engine, just like the B series in both the Ram pickups and medium duty applications are the same basic engine. With both engines the MD applications have lower horsepower and torque ratings to achieve better longevity ratings. The ISB in a medium duty application has a max hp/torque of 325/750, considerably less than the light duty pickup application. The same appears to be true for the ISV.
