As far as I am concerned TMP was much better off without the reveal of V'ger as done in the DE. It was more effective for the audience to get glimpses but never know quite how it all fit together. Like it was just too big to comprehend. It made this entity seem more threatening and unknowable, as a vastly powerful but completely alien intelligence should be. The revealed model, as weird and alien as you try to make it, is still going to look like a model.
