No, because they could just command them to smile or tell how their feeling. On the other hand, present is a very base command to present yourself to your/the dom. It is more you exposing yourself in a vulnerable way to the dom that (hopefully) you trust. I don't really understand how you connected present with smiles or showing emotions. (=・ω・=)
In the bdsm community present is showing your Dom a part of you to show submission. Present with anything other is not showing the true command at all. Present can also be sitting on your knees with palms up as well since you are presenting to your Dom that you are vulnerable and submissive to them. A smile or showing telling your feelings won't show that command correctly. If you'd want a sub to speak honestly, you would just command them to speak honestly. Same with a smile. But present itself means to present yourself in a submissive way. Hope that helps! (⌒▽⌒)
present could be so many things, but they always show the same sexy pose. with him holding his face like that, i would have thought present could be like smile or present some emotions such as joy. which could be an interesting and yet scary way to view the world.
