While the current effect is usable, an improved version (likely introduced later) wouldn't be bad. 
Given that the Black Holes got a Interstellar make-over, how about giving wormholes an appearance based on the same science (though quite a bit older than that film).
EVE has used the same science that forms the basis of Interstellar's Black Hole visuals.
The effect is quite gorgeous in person, with the destination being faintly visible on the event horizon and a distortion effect around the sphere.
