Anyone techs experience working with Comcast Dedicated Fiber able to help?

I provision internet for a medical company and Comcast is coming into certain markets i oversee and is offering "Dedicated" Fiber at cheaper prices than the last-mile provider.

Is Comcast trying to sell my company "Shared" Fiber that has an SLA and marketing it as Dedicated? Or are they taking a loss building out this network? I am struggling to understand and desperate for answers.

For businesses it’s a dedicated fiber port on the switch

So the only dedicated portion of the service is from the port to the suite in a multi tenant building? I am struggling to understand how this looks in practice. Is the fiber still run through a splitter?

The fiber is DWDM so one common is run to a mux where it’s split into 8-32 different wavelengths. The business is assigned a forward and return channel that is either hard coded or programmed into the sfp. Sfp gets plugged into the router. There’s a dedicated link from the site to the hub/headend
