~~Methane needs 5-16PPM [PDF] to be detectable with human smell. Atmospheric Methane is at about 2ppm. So the vast majority of people would not notice a difference. ~~
methane doesn’t have an odor, you linked to the data sheet of trichlorofluoromethane, a completely different molecule
The gas in your house is artificially made stinky so that people would notice leaks and blow their house up, which happened a lot back when the stinky chemicals weren’t added and it was odorless
I wonder if our current world has a specific smell that people from the 80s would notice
There’s more methane in the atmosphere now. It probably smells like a fart.

That’s what I get for moving quick, thank you. I guess the overall point that methane will not make the atmosphere smell still holds
I’m hoping car exhaust takes that role.
People from the 40s would recognize the current smell of the world.
I feel like it’s probably the people from the ~1880s-1920s would know the smell of the world today
