The details matter, but they were probably omitted to have the audience appeal to a wider audience, be more sponsor friendly (good job VW for getting in on the image) - and to avoid the inevitable "Trigger warnings" that come from dealing with real trauma.
For example, I've watched "Girl, Interrupted", exactly once. That is all the times one needs to watch a film with such high impact in order to get the point, be moved, understand (to some extent) - the trauma, horror, and misery experienced by the characters, and I don't need to ever watch it again.
What feels like the intentional sanitation of cinema and storytelling in examples like the one you gave above feels like a creative field that is afraid (be it for financial, censure, or other reasons) - to truly explore the breadth and depth of the subject matter they are studying - unless, of course, they are trying to avoid scandal, by creating scandal.
What I mean by this is - what sort of message does it truly send to victims / survivors / those who aren't quite sure if they're being abused? That it is okay to not quantify the extent or fully explore the impact in order to devolve the whole act into a "she said, he said"?
