How do you call Unity to distinguish it from Unity 2D?

If I've mentioned Unity 2D in a sentence and now I would like to mention Unity and distinguish it so that it will be clear that I'm talking about Unity (the accelerated one) and not Unity 2D, how should I call Unity?

"Unity 3D" is just wrong.

Solution 1:

Unity3D is not wrong, its commonly used to distinguish Unity from Unity2D.

But Unity is the official name of the desktop session and Unity2D is the official name for the non composed desktop session, that should be enough to distinguish them.

Solution 2:

Usually just 'Unity'. As long as you specifically call out Unity 2D, I don't think you need to specify Unity as being accelerated
