How it works:
Hidden below the End Island is a cylindrical tunnel made of sculk and frog light.
The teleporter doesn't port to the ship right away, but inside the sculk tunnel, causing you to fall down inside it, creating the warp effect. To make it more "warpy", another command block gives you the beacon's speed-effect for two seconds, increasing the FOV during the fall.
After 2 seconds, another command block ports you on the ship, and the FOV is reset to normal.
EDIT: Forgot to add the speed effect detail.
