I like this

Spectral Rendering. Also its something that is not available on even commercial
platforms (C4D, Blenders Cycle) in such quality.
Possibly it could be integrated into POV-Ray with not much effort?
Secondly I have a question on the Topic COlor Management:
"Filmic Color Management in Blender | HDR Tutorial (4/7)"

How is this solved in POV-Ray?
