Has E! made a movie telling the true story behind CHiPs?

Did Larry Wilcox have a legitimate gripe against the producers, or were the producers merely giving Estrada the attention he deserved because his Ponch was perceived to be the exciting, sexy, non-Anglo character by female viewers, while Wilcox's Jon Baker was a boring white guy? What ultimately lead to the declining ratings, a decrease in the quality of the show because of the constant cast changes (and a loss of quite a few of the minor characters), or the loss of the rapport between Jon and Ponch? Maybe Ponch wasn't such a dominant factor in the show's success as the producers thought, regardless of what some female fans might have thought?
