Heck, even before you take into account differing xenobiologies, this has precedent on earth; different cultures are often unused to how other cultures smell.
I'm sensitive to smells and perfumes so any culture that uses them often is difficult for me. Hey are there scent suppressants I can buy or is that future tech?
There would so be a market for it, although I'd rather have the artificial odor market be killed off instead. Saves a lot of waste as well. (as the air pollution, those smells... yuck)
I remember reading that some astronauts have reported needing to get used to the smell of Earth again after being in space for a while. Apparently the planet just always smells faintly like shit and we've been ignoring it.
