Thank you David, much appreciated!
LuxCoreRender is a joy to work with because everything, including the lighting, behaves exactly as you would expect in the real world. A back light really casts that broad, bright rim it would cause in real life. I love that. Compared to LuxCoreRender, Cycles suddenly feels like a semi-realistic renderer, floating somewhere between Eevee and Lux.
In other words: I won't be using Cycles anymore.
