What gets revealed to you is controlled by you. That is the difference. The experience of the Brother of Jared demonstrates that if our faith is sufficient all things must be revealed to us. With sufficient faith God can't prevent us from knowing or seeing. So, it is not about God preventing us from something or God not giving to us something because God doesn't deem it necessary for us. God treats us as His equal and is ready to give all things and to reveal all things to whoever is ready to receive it. And the condition of being "ready" is controlled by the individual, not God.
Mankind doesn't operate the way God operates. Mankind's ways are not God's ways. Mankind looks at status, position, titles, and other external criteria.
