What is expected behavior for logging byte arrays smaller then 1 Kb?

When the file is smaller than 1 Kb I got value "System.Byte[]". When the file is bigger than 1 Kb I got descriptive value, "255044462D312E370D0A25B5B5B5B50D... (2296396 bytes)", which is fine

I taught that smaller than 1 Kb values should be logged as complete value? Am I doing something wrong?
