>Based off of what?
The timing of the barrier's explosion/dissipation seems more in line with Demogorgon's evaporation than the railgun hitting the barrier. At the beginning of the game, the dropships produce their own barriers and when they are hit, we see the barriers react. So, we have an idea of what it would look like if a barrier was directly hit and that's not what we see with Demogorgon/Spire 4. The other thing is that the barrier seems perfectly aligned with the position of Spire 4. It looks like a barrier protecting Spire 4 rather than something else.
>You're assuming that the cloak was destroyed
Well, if the cloak shrouding the entirety of the Colony wasn't removed in that single instance, then it's hard to say that was proof that the Colony is cloaked. The Colony may be cloaked, but that dissipation of the barrier near Spire 4 wouldn't be evidence to that idea. The Colony being completely revealed at the end of the Return to the Colony ending would have nothing to do with the barrier that was destroyed near Spire 4.
