You know what, I think comic book writers that put paragraphs of narration in every panel have the right idea actually. Combine the benefits of the visual and narrative mediums!
Have the omniscient narrator tell of information that would be difficult to convey in character. Tell me those worldbuilding details or mention how a character hates something without letting it show on their face. And combine it with art and camera angles to let us directly see things or have our eyes drawn towards certain details.
Also, imagine the unreliable narrator potential. Have the POV narration obviously not match up with what's happening the panel. Or reverse it, have POV art that doesn't match with the omniscient narration. Or do some combination that makes it impossible to tell what's real and what's filtered through the lens of the character.
