"Perfect compression" doesn't make sense anyway. Perfection of
compression (as with entropy) can be expressed only relative to a specific
probability distribution of possible inputs. Once you have specified
such a probability distribution, you can evaluate how well a particular
compression algorithm works. But speaking of absolute compression or
absolute entropy is meaningless.
