Storley refused to be drawn into a brawl as he utilised his wrestling abilities to dominate Page for the majority of the five-round bout.
The American claimed the vacant welterweight belt via split decision, with just one judge giving Page a 48-47 advantage.
The fans made their feelings clear at the end of the bout, with many booing the new champion for his approach to the fight.
However, Storley hit back in the post-fight interview, saying: "The fans are mad at me, I appreciate it.
"Boo me all you want, that guy is talented. Don't boo me for winning.
"I've trained with a lot of people but I have never felt that speed and distance. It is so awkward. He is playing basketball in the middle of the ring and hitting you at the same time. That guy is unbelievable and I had to do what I had to do.
"Boo me all you want, I am a world champion."
While Storley did little damage, his wrestling allowed him to neutralise MVP and keep the 35-year-old off his feet for long periods of the bout.
The American will now return to the United States with the interim belt and target a fight with Yaroslav Amosov - who is currently in Ukraine - for the undisputed crown.
