Ha ha ha. No. Not even a little tiny bit. I think that's along the lines of dismissing any art that doesn't have a recognisable figurative subject in a popular style as "not attractive", and saying that people who buy Thomas Kinkade or Robert Bateman want art that looks "nice" and people who buy Julie Mehretu want art that looks "interesting".
The most significant thing about actual niche perfumers, to me, is not expense or exclusivity, but the fact that they are not so confined by the demands of shareholders and marketplace, and thereby restricted to what is popular, or what does well in focus groups, or what is defined as the "global fragrance trend of the year" by (coincidentally!) the companies that make the artificial esters used in fragrance. A genuinely niche company or independent perfumer has the liberty to follow her or his own instincts and tastes, and to play with combinations that may not be sanctioned by tradition or fashion. And sure, sometimes that may end in a place that is more interesting than pleasant -- but just as with modern or experimental art, a lot of it will be beautiful as well, if perhaps in an unexpected way or a way that hasn't been done before.
And then that will be appropriated by the popular market, just as modern art was and is -- to the point that you can see abstract "art" prints on the wall of your local McDonalds.
(My opinion, of course, may be highly influenced by the fact that I don't, actually, find most popular fragrances smell nice or even pleasant to me -- indeed, I find the vast majority of them unbearable.)
(Moreover, I think a lot of people who buy name-brand fragrances aren't even buying them because THEY think they smell nice. They buy them because of the name, or because all their friends have bought them, or because the beauty blogs they read flog them hard and they want to stay on trend, and they don't particularly think about the actual scent as long as they don't find it actively offensive. I used to do this in high school myself, trying to fit in; the trouble was that I would then find the fragrance offensive when it was in close proximity to my person.)
