On this understanding of psychosis, there's no basis for judging psychotic perception delusional.
There's also no basis for judging anyone as psychotic since this requires knowledge of reality, namely, knowledge of the reality of "the structures of their particular culture" and of the "structure" of the person who is the object of the judgment. Reality, however, is an unknowable thing in itself where perception is determined by "structures" in this sense.
The only relation this can have to psychoanalysis in any reasonable sense is that such a psychoanalysis might be able to explain the psychopathology involved, a psychopathology characteristic of the "particular culture" in which it's widespread.
