My useless guess answer would be "no", only because I can't seem to find any info suggesting they do. However, if I was going to be screamin' down the Pyrenees at insane speeds in a pro peloton, I'd want my wheels as straight and balanced as possible to avoid speed shakes and any other disruption from pending doom! I might be surprised though... I'd assume that if maintaining bikes is your living, perhaps you'd be a bit more extreme about bike maintenance than the average Joe.
