The simple answer in my opinion and experience is yes. However that is not
ALWAYS the case.

I think sometimes the winery does not get all the corks in bottles
perfectly. I have found that if there was heat damage that is the first
sign. Other signs that include the foil capsule will not spit. That juice
has come through the cork and carmelized to the foil capsule. You might see
signs of leakage on label or capsule.

If I were in a retail store and the cork was up at all I back off as a
precaution. But that does not mean 100% that it was damaged.

My opinion.
