Bulless added: “It’s an amazing thing to happen for a lad from Hull and for our students to see.
“That is just something they can take with them now on whatever they are going to do next.”
In an interview with BBC Radio Humberside in October, Aramayo spoke about being “lucky enough” to be involved with Hull Truck Theatre during his early career.
Commenting on his achievement, the theatre’s artistic director, Mark Babych, described it as a “jump up and down” moment.
“What an incredible result,” he said.
However, he said he was not surprised as “Rob is a phenomenal actor”, adding the recognition was also great for “theatres like ours” and the role they play in encouraging young talent.
“We are just incredibly proud of Rob, who is clearly an enormous inspiration to people,” he added.
Babych said Aramayo had also demonstrated “a great deal of authenticity, respectfulness and insightfulness” in tackling the role.
