This is covered in the discussion in different ways and from different angles, but okay, let's define "perfect" for the discussion then: A picture representing the actual conditions of the situation in the most realistic and technically optimal way possible.

OK but is it what you are looking for in a picture? Is the "most realistic and technically optimal way possible" the ultimate goal in photography? To me , you make a confusion between the mean and the goal (or between significans and signification if you prefer).

Take care.
