Is “The official history simply records the rehabilitation of Yue Fei, while the novel dramatizes a grand scene of rewarding the Yue family army with titles and honors” true?

In reality, he was a real general or minister. The History of Song, Biography of Yue Fei, says: 'Emperor Xiaozong decreed to restore Yue Fei's official rank, rebury him with proper rites, grant one million in cash, and seek out all his descendants to give them official positions.'
