Maybe, but not necessarily.
I think different cultures can share the same reality, though filtered through different lenses.
If two people from different cultures watch the same movie, one finds it ok and the other offensive and disrespectful, that's a shared reality filtered through different cultural backgrounds. Even if either version of the movie is dubbed, censored, or altered in any way, there's still enough common or shared material that a discussion can be held.
If two people had completely different experiences and watched completely different, tailor-made movies, then there's very little for them to discuss or even disagree with. "I haven't watched your movie", "I haven't watched yours either", "Mine was better", "I guess... I wouldn't know, I thought mine was cool", etc. No shared reality.
