The soap opera effect has nothing to do with OLEDS.
It is to do with higher framerates on movies than we are used to, making movies look like cheaper filmed tv shows. Not a specific display technology working differently.
Peter Jackson famously had this issue when trying to show The Hobbit in 48fps, and that was in projectors in theaters.
Notice on the wikipedia page for 'Soap Opera Effect' it doesn't mention the term OLED once.
