Why do histogram equalisation programs usually not produce images with flat histograms?

All it does is to redistribute the gray levels non-linearly. It's not flat because the image quantized into gray levels. If it were continuous, it would be flat. However, there are ways to get a flat histogram. See my attached demos.
