Yes, but it's an extremely expensive representation for rendering.
For stylization, I'd imagine you could get close-enough results with a screen space technique if you can get some additional custom render pass buffers from the engine (material properties or whatever is most useful for the specific look). That's feasible in realtime on current hardware.
I presume radiance fields can be generated from computer graphic scenes? It would be awesome to choose your own style while playing a video game! Real-time generation is unlikely, but game replay videos in a surreal style would be trés cool.
