Emulator

If the game is rendering to a 2D plane, then there might not be anything we can do about this.

To clarify what "rendering to a 2D plane" means, the game might be making an EFB copy (basically a screenshot), then clearing the screen, then drawing that EFB copy over the whole screen. (It might do this for post-processing or bloom.) If it does that, then wireframe will only show the shape used for that line final draw (or rather, anything after the clear), which won't show much. This is an inherit limitation of wireframe and I don't know of a good solution for it.
