It probably depends a lot on how the system is prompted. One of the interesting things about generative images is how easy it is to know what something looks like without being able to describe it.
Longform text is likely similar where there are a bunch of interactions and scenes that humans pick up on if they are there without being able to describe. The early Game of Thrones series was a fascinating example of good writing because most of the terrible things that happened to people were a neat result of their own choices (it had a consistent flawed character -> bad choice -> terrible consequence style that repeated over and over) - but I don't think most people would pick up on that without it being explicitly pointed out. And when that started to go away people could tell the writing was falling off but couldn't easily pick out why.
A hypothetical LLM could be prompted with something like that ("your writing is boring, please make consequences follow from choices") but it is less clear that the average prompter would be able to figure out that was what was missing. Like how image generators often needed to be prompted with "avoid making mistakes" to get a much higher quality of image; it took a bit to realise that was an option.
