Hi Steve, yes, I checked. With BBF there is no AF point marker in DPP. If normal focus (on shutter release) is enabled the AF marker appears in DPP. This was using a dedicated AF ON button on a 5Ds and with a specific off-centre AF point selected. Also I noticed (to my great annoyance) there is no actual AF point confirm using manual focus on those models using an LCD information overlay on the viewfinder. You get a focus confirm but the actual point where focus is reached is not shown. This is a pain using a TSE. On the 5D (and presumably 5D ii) with manual focus all the points achieving focus would light which was useful to show the plane of focus using tilt. I've moaned about this before so sorry for the repetition.
