I actually think that a lot of the changes between the 2008 and 2013 versions are more as a result of moving from SD to HD, including some of the detail and the colours. However the change of Antartica to orange is a sure sign that it is a different render.

I'm not necessarily sure that this is the case. As was mentioned the other day, the original 2008 edits got a HD airing during the 2012 Olympics when network news was coming from just outside the Olympic Park - and that featured the original colouring. And, in terms of colour differences, there's probably as much (if not more) between the two 2013 versions than between them and their respective 2008 versions.
