3D is most obvious when it'd used to visualize physical objects or environments.
Abstract information spaces are hard;
being non-physical and having many more dimensions.
The added interface complexity usually doesn't justify the gain, from only throwing away 23 dimensions, instead of 24.
There might be useful ways to represent clusters of information related to a non-physical task effectively; there hasn't been a clearly successful one yet.
and no, if you are trying to jam a bunch of 2D screens in a 3D environment, you are not "representing physical objects or environments" as identified as the core strength above.
