FWIW, PDF format is a mix of sections of uncompressed higher level
ASCII notation and sections of compressed actual glyph/location data

The PDF spec allows compression of the "text" sections - if a PDF is
uncompressed, it's a good candidate for delta & compression.
Unfortunately, within the same file you might have an embedded JPEG.

Sure, all I was pointing out was that even pdfs with compressed page
contents can look like uncompressed text from looking at the entropy
of the first 4k or 8k.
