Currently NeL only supports cubemap water reflections. There's also support for a rendered environment cubemap, but this is not satisfactory, and was never enabled. All the requirements to implement planar water reflections are already in place now.
Planar reflection prototype:
Existing environment rendered cubemap from a good angle (skybox only, not enabled in production):
