The trick is to stay out of product meetings and not actually care how cool and interesting and useful the product can or will be. Only give feedback to your inner circle (manager, peers) when asked about it. Most importantly, enjoy the tasks assigned to you however dull or basic they may be after you mastered them. Be proud of your work.
EDIT: These are things to do together if you have no agency at a company to change it. If you need help getting agency, work with your manager to get data to back up your arguments.
