Nope - and I don't think they ever will be.
They are on the rest of the UK tour because certain seated areas haven't sold out. Also the fact that Groupon are selling GA suggests that 97% of the Lucky Dip will also be GA, and the other 3 % will be across Diamond, Gold & Seats.
Hyde Park is all standing and only 3 price bands - Diamond is long gone, Gold can't be far off and that just leaves GA.

At best you'll get a Groupon deal for the GA tickets in a couple of weeks
Even then, it's a "festival" of sorts, so I can't see AEG letting tickets go cheap.
