I saw a post about Nooelect sellings the dvb-t2 dongle and that it is slightly wider bandwidth than the plain dvb-t dongle.

Looking up DVB-T2 on google, it indicates the bandwidth is 8MHz. There is a plot on the older DVB-T wiki of a DVB-T signal at about 7.5MHz bandwidth.
So the question is why do we only see +/- 2MHz? The dump1090 program would benefit with more bandwidth.

Because the bandwidth in the spec is the one when you use the integrated hardware DVB-T demodulator that's onboard.
When using it as a general purpose SDR you're using it in a completely different mode and the limitation comes from there.
