So I then try printing it and it prints like it looks in Acrobat...  So the colour match from the Acrobat to the Printer seems fine.  Why does scribus think the photos need to become darker when its exporting them?  Surely they should be rendered darker on the scribus screen....?

You shouldn't use PDF X-3 unless you really need it, and this depends on 
having the color profiles for the final device where it is printed. The 
appearance on screen is not so important, ultimately you are interested 
in the final printed on paper result. I could be wrong, but I think it 
would not be recommended for web viewing. Other versions, like 1.4, may 
look washed out with the dark colors on screen, but when printed may 
look fine.
