I'm using version 9.2 of GhostScript on Windows and that is producing consistent results with any type of pdf file. On RISC OS I get a
believable result if I use a pdf file that has been created on Windows
with colour in CMYK format although a little oddly the results are
slightly different from those produced on Windows with the same file
which I would have expected to be the same.
However, much more of a problem on RISC OS is that with a pdf file that
has not been created in CMYK colour it reports exactly the same
(incorrect) figure for each ink instead of giving the correct
proportions. Running GhostScript on the same file on Windows gives a
correct result with the usage of each ink being different. Can anyone suggest what might be going on?

How strange. It appears there are two devices, 'ink_cov' and 'inkcov'
which follow different code paths: https://github.com/ArtifexSoftware/ghostpdl/blob/master/devices/gdevicov.c Are you sure you're using the same one? Also, are you sure the DPI is
the same (default is 75 dpi) and not getting set by some config file
maybe?
Otherwise I'm wondering if there's some undefined behaviour in there somewhere, but I can't see anything obvious...
