My thanks to everyone who has answered this. Leading me into some interesting reading!

I have, of course, considered monitors - I basically use a good, old-fashioned IIyama take-up-just-about-all-of-the-table monitor which had a good reputation when I first bought it and still appears to be correctly set up (plus various monitors at work). I also have looked at most of the photos on a Sony Vaio laptop - so two different technologies showing the same problems with specific colours - which HAVE to be related back to the images as stored by the cameras.

The thought that this could be related to compression is interesting - I have always saved as high-quality jpegs (sometimes tif if available, which it is not on the new Olympus) but I have ignored the RAW format possibility. I shall look into this and see if it makes any diference. Apparently no Adobe RGB/sRGB choice.
