Yes a professional wine taster told me just the other day, "this is very good, not a style I like, but classic x.". If I asked them "Is this a good x?", they could tell me it was. However if I asked them to recommend a wine, they are unlikely to suggest x.

Taking this further, wine experts usually specialise in a particular region. Learning the wines of a region like Burgundy is a lifetimes study. If you ask a Burgundy expert for a wine around £50 to go with shellfish, don't be surprised when they recommend a Meursault. As an expert in New world wines you might get very different answers.
