Thanks for the reply David. In actual fact I don't normally push my skies to that extent. I tried the experiment to see if these oddities could be made visible.
I tried an experiment and took samples of colour from what I considered to be the most saturated sky I would accept and placed dots of these colours on layers above the Granger image I posted. I then moved them around until they disappeared against the rainbow to see where those colours resided. In all cases they were well outside the problem areas. I therefore agree with you that as far as photography is concerned the anomalies are meaningless.
Certainly the Spyderprint profile is a huge improvement on the Innova supplied profile with open, unblocked, neutral shadows. The Innova profile had a greenish cast going into the shadow areas.

I used the 225 + greyscale charts so I may give the 729 a try but it looks as though it may not be worth the effort.
Incidentally I chose to use the Ultrasmooth Fine Art media setting in driver as recommended by Northlight Images. When I initially tried the Velvet Fine Art setting recommended by Innova it was obvious it was laying too much ink on the paper and produced a dark muddy print.

Thanks again.
