Sky effect from Java edition to Bedrock edition.

My idea for a new feature in Minecraft Bedrock edition is a sky graphic effect from Java edition where if you go below y=61 in height there would be a dark flat plane at the bottom half of the sky that appears and between the heights of y=-32 and y=-64 the brightness of the sky gets darker and darker until when you reach y=-64, it's completely black.

Another thing is in a super flat world, The dark flat plane at the bottom half of the sky appears at y=-64 and the sky fading effect goes from y=-63 to y=-64.
