If you jump outside the ocean and fall into the abyss, you can see the entire skybox. The skybox consists of two distinct halves:

The upper half features the skies

The lower half is a solid color that changes dynamically based on the time of day (day/night cycle)

Issues:

The solid color on the lower half of the skybox reflects on spherical objects. However, these objects do not reflect Genesis City

The ocean may not render from a long distance (if you are standing at the center of Genesis City on a high platform and trying to observe it)

Even when standing on a cliff, the horizon still shows the layer of the lower half of the skybox

Temporary Solution:

To lower clouds level (to avoid horizone line) and to replace the lower half of the skybox with a blue gradient that transitions from the center to the bottom, gradually reducing blue saturation and apply on it dynamic Exposition to be compatible with a day/night brightness

In adition, would be great to remove half of the clouds, to keep clear weather periodically.
