I see, thank you B.Y.O.B.
I had it running for a 1 hour with classic and there is no black center visible.
Maybe it's something with curved surfaces and too huge VM start radius.
Shortest edge length in lens element is 0.000005476, i set the start radius to 0.000005476 and see what happens, classic already works so why not for the shake of curiosity.

Does the 32 bit float limit matter in luxcore in terms of what's on hdr map times gain?
I will check this next, gain down and use instead camera shutter speed compensation.

32bit limits are a lot largest than 16bit but are still there so it is still possible to go out of bounds.

Limiting the maximum float to 32bit range didn't work out.
Maybe there are some nasty small floats, image editor can only show me 3 digits after comma 0.000, but 16bit limit is 0.000061.
I will add 0.0001 to hdr map.

edit
The hdr map that was edited to 16bit float range was exported to exr unchanged by Blender 2.79b and filesaver engine. Sun keeps it's dynamic range / values.
