You are not being self-consistent. If art is defined by the creative process, not the end product, why are you measuring its quality by the transformative power of the end product?

I also don't think your (very strong) assertion that AI art products have no transformative power would stand up to any sort of unbiased, blinded comparison. Art's transformative power on the viewer comes from the effect of the art object (the end product) on a human mind, and it's possible to get that effect while knowing absolutely nothing about the source of the art object.
