I guess that makes more sense now that I see an example. I just can’t fathom how any Apple artist thought they made a “grinning face with smiling eyes” when they looked at that image. It’s “grimacing face with smiling eyes” very obviously. I thought all representations were like the others in this example - they all look like a “grinning face with smiling eyes”. They look different but it doesn’t matter.
I still think though that if there weren’t obvious mistakes like this, it doesn’t matter how the “grinning face with smiling eyes” exactly looks, or any other emoji for that matter.
