Vibrant Visuals doesn't work in splitscreen

If I play the ‘'vibrant visuals’' in my own world whit nobody else, everything works amazing good. but when I play a world an someone else joins in splitscreen on the same PS5, the ‘'Chase the sky’' update works and everything is there. But the vibrant visuals update, nothing is seen. The vibrant visials are not working. if I play on the other account in a world, alone. everything also works.

So only the vibrant visuals are NOT working if I play whit someone else on the same device in splitscreen mode.
