I feel like it'd be weird because it usually does smell neutral after a time. You notice smells off of your baseline but typically you're just unaware after a while.
I read somewhere it's likely an adaptation to help us notice dangerous smells. You're more successful at avoiding fire or poo (germs) etc when it stands out, which is easier when the baseline is neutral.
After a certain point you kind of get used to the smell of fire, though, too

Well, if you can smell something for days and stay alive then the smell becomes neutral (as in the source doesn't actively tries to kill you)
