Per the United Contract of Carrige, HPN and LGA are consideded to be the same point. As such, a destination change from LGA to HPN is not considered an involuntary reroute. Hence, UA owes you $0 for that.
UA may give you something for being at the gate and not being let on the flight. 15 minutes early is excessive, even for UAX! The line has to be drawn somewhere. If you do contact UA, focus on the DB and not on the "reroute". It would help to have some proof of being at the gate ontime (next time this happens, have someone take a picture of you at IAD with an airport clock in view

)
If it were me, I'd drop it. Than again, I will not fly on a flight in or out of IAD.
