Looking over the Deluxe description in my cruise planner for a sailing next week, the answer is no. It includes their lunch buffet and admission to Blue Lagoon with transportation. The video header is highly misleading as it's showing one of the dolphin encounters. You'll be able to observe from afar, but you don't get to sit next to the dolphins without a dolphin encounter package.
 

Thank you so much USCG Teacher! Your comments and great description of your experience at Blue Lagoon is extremely helpful Much appreciated!

Hi @RDCruise!  I actually did this excursion and wrote about it in my trip report here:
I did not mention the ferries/water taxis, but yes, they were a very smooth and comfortable ride. They were of varying sizes and the seas were pretty calm the day we went, so that may be a pretty big variable, but certainly had no complaints on that front!

I think of the food at the MDR as a really well done catered event.  Kind of like an expensive wedding where there are several choices for entree's. The food is great, but it is cooked for a very large group which limits the quality.
Specialty Dining offers a cooked-to-order menu which allows for higher quality.
In my opinion, both are very good.
Although there is an Italian theme night, there will not be anywhere near the choices offered at Goivanni's.
