Does Future Lighting Works InGame?

I have read a lot of posts about Future lighting still being in beta and only working in Roblox Studio.
Now was I just building and doing fun stuff, and wanted to publish and test it. While building, I had put the lighting on Future, so it also published with Future lighting. When I joined I realized the lighting, and I was wondering if this was only for me or also for my friends, so I invited a friend to my game and called him. He also saw the Future lighting.

My Question:
Does Future lighting work or not and if it does work, for whom?

My theory is that it only works for people with Roblox Studio and I cant support my theory with facts, just a guess lol.

Here’s a clip of the game.
And here is the game itself.

It’s been live for a month now.
