Thanks to all who replied. I've found that the best results are obtained by disabling Colour Management completely.

For the record, I've discovered that, at least with NEF files, the Nikon software creates an icm profile on the fly, and it is different for every single NEF file. Hence copying icm files from the Nikon software is a non-starter.

However with colour management disabled I'm now able to get results comparable to those achievable with Bibble, just by using Digikam.
