I added the blue tint for a few reasons, mainly so the shot matched better with the Exegol ones and didn’t feel so visually jarring. Whether the implication is it’s supposed to actually be Exegol, I think it’s open to interpretation. Also I see it as sort of an obscured version of a future event, we can’t quite tell where exactly that moment is going to happen, so you’re not giving away the transport scene too early.

Anyway, with the yellow, I think you could make a reasonable argument either way whether it should be in the vision or not. But it would sort of clash with the massive lightning blast so I’d probably be against it.
