Not quite, I believe the reason for wanting the wedding televised is purely for publicity and to be seen as being as important as the Cambridge and Sussex weddings were.
This, together with a two day long wedding celebration, the involvement of the Scots Guards based solely on the link of Jack's great grandfather being in the regiment, fairground rides, insistance on a carriage procession, and a very large number of celebrities in attendance or even performing would, IMO, point to a very big effort to be in the limelight.
I'm not sure if it was Eugenie or Beatrice who was exposed a while back as earning £19k a year for working at a technology company, but one would expect someone who has actually worked in a low paid job in the real world like many of us have done, to have a better understanding and appreciation of the huge expense involved in the whole two days.
