"A lot of it has changed as well. You can go on there with an instrument," Henderson told BBC Newsbeat. "You can play and there's just a lot more artistry to the show and that's great."
She added: "We've got somebody like James Arthur, who won and he's an incredible talent.
"Everybody was so different this year and so diverse and I think it just shows the show is a credible show at the end of the day and that people have come off it who really do take music seriously."
