The main catalogue for the UK is essentially the same as the German one, without the Funpark promotion on page 2.
Comparing the US and German [k/c]atalogs I found 11 pages with differences (whole of pages 2, 4-5, 52-3, 65, 66-67, half of pages 21 and 71 and one extra set on page 33 of the US catalog). On most pages, the three catalogues differ only in the text printed in black, which suggests that the inclusion in the US catalog of sets not available in the US is a cost-saving exercise, sadly (cheaper to include the colour pictures from the German Katalog than print a whole new page).
Is the Octopus figurehead in set 71530 (pages 26-7) not a new animal, Tim? Or is it a cling-on? Which reminds me, what happened to Star Trek sets?
The 50th anniversay sets (page 3, all cats) are frankly disappointing. But maybe I will be able to get some replacement aerials for the old cars...
