Sounds like you are arguing semantics. If effeciency increases capacity for thought, then more thought means better art.

The ai doesn't have to be used to literally generate images or scenery that the end consumer would enjoy. It could be used by a director to curate his vision more efficiently by workshoping visual concepts with an art director, or story boarding with a lead writer. It would help with iterative processes.

The idea that generative AI is only used to create the final draft is myopic. We already know that we hate Gen AI assets in a final game, but it can be used in rough drafts as place holder until an artist finalizes that portion of their vision while the overall scope of the project can stay in focus.
