If you notice under the listing on the website, it says Concierge-level Guests also receive these special amenities:
Ability to participate in the Wildlife Discovery Excursion an exclusive guided tour of Kilimanjaro Safaris® at Disney's Animal Kingdom® Theme Park offered only to a limited number of Concierge-level Guests for an additional fee.
It's not the sunrise safari. This one is called the Wildlife Discovery Excursion. Here's a brief description:
LAKE BUENA VISTA, Fla. -- Walt Disney World Resort concierge-level guests can venture off the beaten path of the Harambe Wildlife Reserve at Disney's Animal Kingdom for a unique wildlife discovery excursion. Led by a seasoned safari guide and an animal expert, the adventure takes guests beyond the safari trail, stopping at special observation and photo areas throughout the 110-acre savannah of the reserve. The excursions begin Feb. 15.
Small groups (no more than 14 guests) travel in a custom-designed, climate-controlled vehicle for the one-hour excursion, offered daily at 10 a.m. and 1 p.m. Cost is $45 per guest with a portion of the proceeds donated to the Disney Wildlife Conservation Fund.
For more information and to book an excursion, concierge-level guests may contact their Walt Disney World Resort concierge or resort itinerary planning office. Advance reservations are required.
It's a little different than the AKL's sunrise safari, as it happens during regular park operating hours and does not include the buffet breakfast. Guests tour the Kilimanjaro Safari in special vehicles. From what I understand, you get a better view of the animals and more opportunity to take photos.
