I enable the 2dgs renderer, and drop the file from the online 3dgs site. The result looks like this. Does this mean that 2dgs is a separate file that the training results are received in, and that the two files are not generic?

If you mean that you are trying to view a normal 3DGS scene, with 3 scale values per splat, with 2D rendering mode activated, then you will definitely see incorrect results :) A 2DGS scene only has 2 scale values per splat.
