Can a surface reflection ignore the physical sky?

I am working on a parody, and would like to recreate the Castle Rock logo: https://www.youtube.com/watch?v=O31jJ7I7qRI

If you look at the video, you'll see that the lighthouse beams move and illuminate the land, the lighting sort of comes up like a sunrise (as a sun actually rises)....

BUT....even though the water becomes more illuminated in general, it does not reflect the world in a normal way. The sun reflected seems larger, and the color and lighting of the water seems to be 100% independent of the sky/environment.

I get that this probably isn't an actual 3d render, but I'm wondering how much of this I can obtain via Max and Arnold. Any time I try a surface with a water-like shader, it (CORRECTLY) takes on the look of the physical sky.

Any advice....I'm THINKING it may involve rendering the water, then just compositing the above sea level bits....????

You should probably be able to achieve this with the Ray Switch Shader.

This looks like EXACTLY the thing! Thanks, Brian..... so would I be right in thinking that I could just save a bitmap to a Standard Shader (with the bitmap being the 'above sea level' lighthouse and land) and then pipe that shader to the reflection of the water?

Apply the AIrayswitch to the skydome light.

I am a Maya user so I am not sure about the workflow but it should be nearly the same.
