Can an advertisement be misleading even when its individual sentences are accurate?
It can. People take in the headline and the image as one promise, so review them together with the offer and the disclosure, and ask what a reasonable viewer would believe the product can do.
The media conversation's example of using real product imagery points to a useful habit: inspect the whole message at once.
Put the proposed headline next to the actual image, offer and disclosure. Consider how a reasonable viewer would read the claim and what they'd expect to receive. That's a review question for the responsible specialists, and you can't settle it as a legal conclusion on your own.
Check the details against the product information. A generated scene can introduce a feature, a quantity or a use the text never mentions, and a crop can remove the qualification that made an earlier version understandable.
Someone outside the process explains it back
Ask someone outside production to explain the message back to you. Note any reading the team didn't intend and look into whether it needs a correction. Then review again in the final placement. The promise comes from the assembled experience, and approving an image and a sentence separately can leave nobody responsible for what they say together.
