Dead give away

I watched season 7 first and now im on last episode of season 6 and during when the last 4 couples go on dates they definitely give away who wins and thats just by the dates. On season 7 amya and Brian's date they got a cute like scrap book and the other people's dates were just basic dates and didnt get anything like that. now on season 6 Kordell and Serena there date they get a movie while everyone else just got a basic date dont get me wrong they were nice dates but nothing like amaya and Brian or Kordell and Serena. Based on those date alone I would have guessed those couples won. Im wondering if thats how it is on the other love island seasons if so then they need to make everyone's date a basic special date and don't be giving 1 couple something way more special then the other dates.
