There's a level of fair argument here, but all marketing is hype, the law only considers it deceptive if it lies about the nature of the product itself.

An iPhone ad will try to convince you to drop two grand on the new one because it has features Android has had for years, but if the iPhone actually does what is claimed, hyped up marketing doesn't make the product itself a scam.

If marketing overemphasising the value proposition of a product makes the product itself a scam, everything that's been advertised could be argued to be a scam.
