see everything
瞶 centers on seeing everything, suggesting a broad, all-encompassing vision or perception.
瞶 combines 目 (eye) with 貴, which likely contributes the sound and may suggest something valuable or elevated, together expressing a high or complete level of seeing.
The eye 目 sees something precious 貴, like a treasure that reveals everything when viewed clearly.
For キ, imagine a key that unlocks the ability to see everything: key -> キ, and with it your eye 目 perceives all.
