In this case there's a difference between CGI and generative AI. However they came up with arrangement of pixels on the screen, the product is still portrayed accurately.

Now, unless the company in question got their new strings into Sona training data, I wager that the generated output has little casual connection with the product being advertised. If I found out IKEA's newest product looks nothing like on the commercial, because the ad was using generative AI and hallucinated something approximating the product, I'd be looking at it as fraudulent too.
