Now one could make a good argument that it fails miserably at revealing information since it is so opaque but that is clearly what it is said to be intending to do.ⓑ of revelations of a particular kind, through visions, etc.: w. gen. of the author ἀ. Ἰησοῦ Χριστοῦ Gal 1:12; Rv 1:1 (w. ὀπτασία) ἀ. κυρίου 2 Cor 12:1. κατὰ ἀποκάλυψιν because of a rev. Gal 2:2; MPol 22:3, Epil Mosq 5. κατὰ ἀ. ἐγνωρίσθη μοι τὸ μυστήριον the secret was made known to me by revelation Eph 3:3. Cp. 1 Cor 2:4 D; 14:6, 26; 2 Cor 12:7.—In the visions of Hermas the ἀ. are not only transcendent rev. for eye and ear, but also the interpretations given to such rev. The ἀ. is ὁλοτελής complete only when it is explained and understood v 3, 10, 9; 3, 13, 4a. W. ὁράματα 4, 1, 3.

So an ἀποκάλυψις differs from a vision in that it doesn't just reach the eyes and ears but conveys information as it is explained and understood. This is not "the vision from Jesus Christ, that God gave him" but as you look at the context this is prophecy that they can act on:Rev 1:1 This is the revelation of Jesus the Messiah, which God gave him to show his servantsthe things that must happen soon. He made it known by sending his messenger to his servant John, Rev 1:2 who testified about this message from God and the witness of Jesus the Messiah. Rev 1:3 How blessed is the one who reads aloud and those who hear the words of this prophecy and obey what is written in it, for the time is near!
So ἀποκάλυψις might better be translated "secret information" and when translated that way is more obviously not about Jesus but rather communicated through Jesus:
"Jesus Christ's secret information that God gave to him to show to his [God's] servants what will happen soon"...
or, probably better:
"The secret information from Jesus Christ that God gave to him to show to his [God's] servants what will happen soon"...
Rev 14:14 And I looked, and behold a white cloud, and upon the cloud one sat like unto the Son of man, having on his head a golden crown, and in his hand a sharp sickle.
Rev 14:15 And another angel came out of the temple, crying with a loud voice to him that sat on the cloud, Thrust in thy sickle, and reap: for the time is come for thee to reap; for the harvest of the earth is ripe.
Rev 14:16 And he that sat on the cloud thrust in his sickle on the earth; and the earth was reaped.
"A few commentators identify the reaper as an angel rather than Christ.They argue that it would be strange for the exalted Christ to be commanded by an angel (as he is in v. 15), and unlikely that he would not know that the end had arrived..."
The commentators in question obviously were Trinitarians that presumed that Jesus was omniscient and were uncomfortable that John so clearly depicts him as needing to receive information from God- an through a messenger no less. But once one does away with the foolish "Trinity" notion all makes perfect sense.
