As others have said, items don’t usually linger on shelves for too long, and if they do, they get pulled. 

But also, when they say “dark” they mean away from sunlight. Your average supermarket usually doesn’t get very much actual sunlight, and the LED or fluorescent lighting isn’t likely to bleach/alter/warm the product like sunlight will.
