Guests on site can access the virtual ques and Genie Plus at 7am and off site guests have to wait for park opening, is my understanding for WDW so I would think that DLR would be the same probably.
No, it won't be the same. They specifically stated that at DLR, ALL guests can ONLY access Genie+ after entering the parks. It will be programmed to only activate after you have scanned into the entry gates, similar to how the system works now for the 12 o'clock Boarding Group drops. If you haven't scanned in yet, you can't try for a boarding group at noon.
