I am not refering to myself or my friends at all.

That said, I've only seen this green vs blue debate reported on in the context of American teens. Even if it is accurate in that group (questionable), that group make up a tiny portion of global smartphone users. Even if the actual group who care are double that, it's still tiny.

As such, it seems unlikely this is such a critical thing that Apple bigwigs are sitting around discussing this group.
