I'll be honest, I feel like the expansion of the BBC News brand here is diluting the brand somewhat.  If everything news on the BBC is branded BBC News, then just what actually is BBC News?  What does it mean to be part of that brand?  I'd rather have BBC World Service News, BBC News 24, BBC Radio News and so on and so forth, leaving the core BBC1 news service as the main BBC News, rather than everything just branded BBC News, making it somewhat meaningless.

Why do the BBC1 bulletins get to be BBC News? What makes them more BBC News than the news channel?

Because they are the most watched, therefore when you say BBC News, most people think about the 6 & the 10 on BBC1, rather than anything else.  Hence, the sub brands actually help identify the source better.  I heard a story and it was only on the World Service news bulletins, nowhere else, so I would say I heard it on World Service News.  Where as saying I heard it on BBC News, doesn't tell you it was on the World Service only, not anywhere else.  Hence, the brand is diluted, by spreading it thinner over more sources.
