You're always learning as an actor... anything you do is a learning experience. It's the same whether you're doing film or TV, you have to do the part to the best of your ability, no matter how big or small the role. It's as simple as that, really. But every bit of work you do is a learning experience - which is the same, I guess, for people in whatever job they do. But with acting, it's also fun to be able to explore different characters and emotions.
