I'll be the first to confirm that at least my EXO-500 Oil and perhaps all newer ones were shipped with the dark smoke sun visor. So, I didn't need to buy the dark smoke separately. I could return it but shipping would cost me about $10 to get $20 back, so I'm better off keeping it, or selling it locally.
It works well, as expected, as I had an older Scorpion helmet with an external dark smoke visor and they are the same shade of grey. Now I have a night and day helmet with no external visor swapping.
