Does anyone know what's going on here? I thought the ident was a model? It looks rather nice with the Black.

I think we need our very own resident bbctechop to explain the full details, but my guess is that although the globe was internally lit, it needed to be of sufficient brightness to produce a reflection. It also looks as though the light behind the lower third area containing the logo hadn't yet been lit until part way through the CA.
