Neither of those are true. From a resort services perspective, there is no difference between a DVC resort, and a normal WDW resort. Keep in mind, that many of the DVC resorts share space/utilites/infrastructure with a regular WDW resort. AKL, WL, Boardwalk, etc. As the villas at each of those locations shares a bus stop, desk services, shops, etc with the normal hotel guests, how could they possibly have less services available.
The only guaranteed difference is that if you are staying at DVC on points, then you get reduced mousekeeping. If you stay using cash, its just like a normal WDW hotel room. The food at some is more limited, (OKW I'm looking at you) but they all have similar pools, amenities, transportation as any other deluxe on property.
It would appear that overall the bus service has less buses running during mid day, only because most people are going to be in the theme parks, not going to or fro, but they still shoot for that every 20 mins timeline.
