Is it possible to meassure the light in (LUX) at a certain point on level surfaces?

I found, that under Show->Visualize->HDR (Eye Adaptation) I can meassure LUX on a certain Point, but I wanna do this further so I can access that meassurment from my own Tool/Plugin/Whatever.

Does anyone has an Idea how to tackle that, caus I can’t find anything about that piece of code or how to access something like it via blueprint or similar.

Thanks so much.
Cheers
