I'm not sure if there was initially an obit ident in the 2002 set. For the death of the Queen Mother they used both a still from 'Ballet', and a blurred photo of the 'Capoeira' dancers, which was the background for menus and was also supposed to the background to the unused clock, but I don't know if it was ever intended to be used as a serious news ident
The intention for an obit was to have a still of an ident to lead lead into the newsflash. Hence when the Queen Mother died, the still of the ballet dancers on One and the still of the Two on the other side. If it had been a few weeks earlier or would have been a still of the balloon
Not sure about the menu backgrounds but you're probably right about Capoeria. It did seem to be the standard flagship neutral ident.
