I guess this is down to the UK Hilton elimination of non brand standard benefits that is discussed on this thread:-

I would guess that this will put the Waldorf at a disadvantage to the Doubletree that can offer breakfast and the Carlton that can offer breakfast and lounge access.
Agree the Carlton will heavily cannibalise business from the Caley, better location and exec lounge along with walkable from the station will be a no brainer for many Diamonds.
Perhaps add your comments about lack of breakfast for diamonds to this thread
