The purpose of advertising is to sell things to people that they don't need and likely can't afford, and that can't be done through truth in advertising.
Spoken like a crook. And there are a lot of crooks and snake oil salesman out there, and this is clearly within that particular genre. But the purpose of advertising is to connect people with a product they might need or want, and to convince them that they need or want it. At the end of the day, if I want to sell you product X, all I can do is talk about its advantages, and how it might help you personally, and I can do all of that without ever telling you a lie. You must decide if you need it / want it or can or can't afford it.
On the other hand, if I do lie to you, and tell you product X will do something it won't, then I have committed a form of fraud, and you have a reasonable civil tort against me. But a reasonable degree of photo manipulation may be expected due to the nature of the medium. Breakfast cereal, for example, is filmed with glue instead of milk because milk goes bad REALLY fast under the heat of a studio light. An image may be photo-shopped to restore definition or color lost in the process of photography. That doesn't mis-represent the product so much as it helps present the best-face of the product. I might reasonably want to show my video game sprites rendered by the best commercial hardware available, but if I render that at colors and resolutions impossible to achieve with currently available hardware, than I have committed fraud. And it seems the NMS developers have done that.
