Years ago I could Image Search a frame of a film and get the film title almost every time, now I get a generic "Street" or "Man" search term and then a bunch of photos that have streets in them with a similar color palette which are never from the film.
They've got so excited by the tech that they can identify an object or setting that they've forgotten just finding the same image elsewhere online and using the context of the web page would give a better answer.
