no I don't think so,
Everytime you lose it's because of a mistake. I've played a professional player once.
In the beginning I tried to see everything and it worked well for a while.
After some further ahead thinking from his side I didn't stand a chance. But I definately learned.
Only worse opponents can be useless to learning I think, and for that, only sometimes.
Even a GM couldn't crush if you pay attention well enough. He will win, and easily, but as you try to give him a hard time you can keep it up for a while.
[ps. it's not like most other sports, you can easily do what your opponent does. You only have to think of it]
This probably will not apply to masters and such, but for us mortal chess players, do you think it is possible to play someone so much better (and higher rated) than you that you don't actually learn from that specific game anymore because you were just so utterly crushed?
Imagine trying to mount a kingside attack against a super GM and having it thrown back completely in your face. Or even just trying to force a winning combination on a regular GM only to realize too late that he has nullified any of your threats while presenting you with so many threats that you are just overwhelmed.
