Probably a stupid question but weren't the titles previously re created in 2012 for the move to Broadcasting House and the transition to HD as standard?

The colours were tweaked in 2013 with the move to Broadcasting House.  The grey shades and darker black areas were given more colour.  This is when the UK version was edited to include the "Trundle Cam".  The Red Box also became an overlay.

I think the World News version was slightly more orange than the UK - but it may just appear that way.

I am not sure if the BBC re-created these, or if they were given higher res versions with tweaks.
