They can control and modulate the injection far more with DI, because they're not limited to intake injection. I cannot give you much in the way of credible sources on the 50% claim from DI, only that I've read it from multiple sources - so treat it as marketing speak.
But even if we're "only" gaining 5% efficiency from DI, it's a pretty big deal. I'm fairly sure a GP3 or GP2 engine supplier have stated that DI provides better mileage, power, and torque, especially with an FI engine, compared to MPI.
