Well known and useful are two different things. Is it true? I would not deny it. Is it worth worrying about, let alone practical or worthwhile to somehow implement or enforce? I would not say so. It is one of the silliest things to consider in displaying a print I've ever heard of. Stand so close that you cannot comfortably view the entire print at once to cancel out wide angle distortions? We have to treat the photos as optical illusions now just because we can't come to terms with a flat image? Astonishing.
