Since miqo'te intellectually appear to be equal to, well, every other race, it's unlikely that they actually have senses being considerably more sensitive than the human baseline.
Additional sensory input requires more brain space dedicated to processing it. Miqo'te brain size is pretty much identical to hyur, so if they actually had a sense of smell that was considerably greater than that of hyur, they would have to lose something somewhere else. Either in their other senses or in their cognitive abilities.
Unless we get into my own personal headcanon about the existence of "chimeric" forms in Hydaelyn, where accidental or intentional aetheric-induced evolution resulted in all the other races originating from the hyur ancestral stock. I can definitely see miqo'te as being a created race, a magically-engineered offshoot of Midlander hyur (or their ancestors) stock designed by A Wizard (probably more likely to be a whole mess o' wizards) to serve a specific role such as hunters, assassins, scouts. It wouldn't even surprise me that much if the Allagan Empire, or another precursor civilization, was responsible for the creation of all non-hyur races.
In that case, it would be entirely possible for miqo'te to have magically-amplified senses that don't have to follow the rules of mundane biology. Considering how high-magic the XIV setting is, this really doesn't seem to be much of a stretch to me.
