FYI: In the UK, the Advertising Standards Authority regulates these sorts of matters:
Don’t mislead consumers materially
Rule 3.1 states “Marketing communications must not materially mislead or be likely to do so”. When considering whether business to consumer advertising is misleading, the ASA will take factors identified in the Consumer Protection from Unfair Trading Regulations 2008 (CPRs) into account, including how the average consumer will interpret the ad and whether it is likely to cause consumers to take a transactional decision that they otherwise wouldn’t have taken.
Marketing communications will be assessed on the overall impression they are likely to give consumers, as well as specific claims and images, so marketers should be mindful of the need to consider the likely interpretation of an ad as a whole, rather than individual elements alone.
An ad for a meal delivery service was upheld by the ASA because the image of the meals in the ad were not an accurate reflection of the meals which customers received (Parsley Box Ltd, 13 November 2019).
