No - the difference in angles between a new piece of tape and a partially worn piece of tape is all but nonexistant. Also, if you did not change tape when it became partially worn, it would continue to wear, creating a difference even greater than if you did change the tape.

So really it's a personal choice thing. Use tape if you want, or don't use it if you don't want to. But if you do, it is better to change the tape when it begins to wear. And changing when moving between hones is a good habit to get into as it serves as a reminder to at least check the tape for wear.
