Yep. It makes sense when you think about it; it's pretty intuitive that the shape of the glass would affect how you smell the wine as you drink, and nobody's really going to contest that scent is a large component in flavour.
Like you've observed, it's not such a large deal that if somebody poured red wine in a white glass and handed it to me, I'd wave off (let alone burgundy in a pinot noir glass or something). But it turns out that stuff like that makes a difference if you look for it.
