I hadn’t considered that the OP might be asking about “recreated live,” but I definitely agree on Images and Words being something that’s almost impossible to pull off live (in terms of the specific vibe on the album that is).
Sometimes on these topics you just have to range wildly.
But seriously, I think being hard to recreate live is a good indicator of a song having a unique vibe, although it's not true in every case of that. A live performance is not as capable of faithfully presenting a specific nuance in the sound or performance as a studio recording. And a band's live performances tend to render different songs from across their career into a more homogenous-type sound. Listen to
Live at Luna Park, for example, and you'll hear songs from
Awake,
Systematic Chaos,
Octavarium and
Images and Words, albums that occupy fairly distinct sonic spaces, all being played over the same basic setup with not a lot of variation in things like guitar/bass/drum sound, and featuring James's one-take live performance on two particular nights of a tour years or even decades after those songs were first written and recorded. The main thing that remains distinct is the songwriting. And if the unique vibe primarily came out of the songwriting, it'll still be there. But to the extent that the unique vibe was in the other elements, it won't show up. (I think the unique vibe on IAW comes partly out of songwriting, and that element of the vibe is still present in live versions, but other parts of the vibe come from factors like performance and production, and those don't tend to come across in live versions.)
