First my version say 2.16 not 1.16.61 on the PS4 but that isn't an option. The big I am seeing is that World generated Underwater I can see fine but anything I place via bucket or /fill command is too cloudy and can only see about 6 blocks diagonal versus 16 I can see in the normal world generated water. The 2 photos are at the same depth, one in a lake and one in a pool I created, both in the same world.
