That's what I'm doing.
The book has things that are wrong in it. Here are two simple examples.
On page 119, the top-right blurb mistakenly labels Wanda Maximoff as Natasha Romanoff.
On page 285, the top-left blurb mistakenly labels Maximoff's children as "Bobby and Billy" when their names are canonically "Tommy and Billy".
Simple mistakes, yes, but mistakes none-the-less. The book can be wrong about things, that's the point. If the movie, ALSO made by Marvel Studios contradicts something a book written after the fact has in it, I'm going with the movie. This is arbitrary at this point. You chose the book, I chose the movie.
