Wolf- these are different levels of perception. Intellectually, yaakov might have been able to learn at a tremendous level, and understood the secrets of Torah.
Emotionally, yaakov didn’t have nevuah and thought Yosef was dead. He did not have ruach hakodesh- he was just intuitively brilliant and understood the sodos of life and Torah. How much greater that he did it all without nevuaj but with his own kop!
