Boldy isn't in the NHL because he fractured his ankle, and he is getting a few games in at the AHL level to knock the rust off his game. The excellent performances(and waiver status) of depth players on MN like Sturm, Pitlick, Hartman and Duhaime will also make it harder for him to get a call up, till an injury or trade happens. Boldy is a guy you want playing in your top 9 and on the PP right away if he comes to the NHL. Otherwise, he is better off getting prime TOI with Rossi and Beckman down in Iowa.
Saying that either he or Newhook are better or worse players with such a tiny sample size is ridiculous. I say this as a guy who liked Newhook(and Krebs, despite his Achilles injury) during their draft year, and was lukewarm on Boldy. At this point they are all babies.
