I currently have a hub 5 and on M250 Fibre Broadband service. When I look at the hub status page it tells me that my Cable Modem Status Online is DOCSIS 3.0 should it say DOCSIS 3.1?

The primary downstream channel is always DOCSIS 3.0. When you Hub is powered on with Coax connected it needs a simple channel to do receive the stuff coming its way. Likewise for upstream. At that point, the sub-channels of DOCSIS 3.1 haven't been allocated and won't be until all the registration formalities have been completed.

Hub 4 & Hub 5 both run a mix of multiple 3.0 channels and a single 3.1 channel,
we can see that is working as expected in the last couple of lines of your post.
