Not sure what you mean by “the text being constructed” isn’t all text?

It’s pretty common since movies became popular in the 20th century to write fiction in a way that emulates that cinematic sense of immediacy, by removing anything that foregrounds a distinct narrative voice outside the thoughts and sensations of the protagonist(s). By convention, readers take this style of narration for granted and ignore that it’s still a construction (i.e., the narrator isn’t felt as a conscious presence creating the narrative.)
