Well, there's also the interpretation of said cheers and/or boos. One could argue that being greeted with cheers means the audience is happy you're out. They've shown the camera inside the house during the cheering, which I presume the remaining HGS can hear, and I've wondered if they perceive that as cheering the evictee or cheering the eviction itself.

I can well imagine Libra coming out to boos and assuming the audience is pissed she was evicted. As delusional as all of them get in that house, I think they're going to interpret any audience reaction (short of "you suck!") as validation that they're loved.
