Worth remembering, too, that deer undoubtedly smell many things that they cannot identify.
Aromas don't have labels on them saying "this is what the new Scent Lok clothing smells like"
I suspect, many times, deer pick up a scent, but don't know what it is... may make them curious, or wary. I doubt they automatically flee when they pick up a new scent.
And I agree that deer that live in an environment close to humans don't necessarily panic when they smell something they can associate with humans- if they did, they'd never set foot in a cultivated field.
