Having read the article, I still don't understand the point of 3D modeling emoji. Even the user interviews didn't mention it, and problems like "what the back of a smiling face looks like" sound entirely self-inflicted.
I was hoping they had standardized how emoji look across platforms. There are still significant differences between Android and iOS, for example. They recognize how subtle emoji interpretation is, so the only reasonable conclusion is that sender and receiver should see the same pixels.

You can't really do this. Or, rather, it's already been done, but people choose not to do this.
Emoji are just unicode characters. How they're displayed depends on the font used. Everyone could choose to use the same emoji font across platforms or apps, but they don't.
The one announced here is open source, for instance, but there's no way Apple is going to adopt it as the system default.
