Not exactly.
From a recent interview, Kevin Feige mentioned that it seems of Marvel Studios seeming to have full creative control of the upcoming Spider-Man Homecoming. But, Sony Pictures will be apart of distributing the movie and that's from other articles from early on in the deal. Sony also has the ability to create other films of Spiderman regardless if its MCU or not; and to include possibly other marvel characters (Phil Lord and Chris Miller are seeming to be writing a upcoming animated Spiderman film for 2018).
