Is anyone able to render this with Luxcore standalone ?
I'm trying with 2.4 official standalone without success.

Not just "super white" materials, any good white paint should be around 0.9. They are usually based on Titanium Dioxide (so is toothpaste btw.)
Real super whites for technical applications would be Barium Sulfate (BaSO4) or "Spectralon" (a sintered PTFE), and they even reach 0.99.

As a side note for the real world: to achieve the high reflectance you need to ensure a sufficient thickness of the paint. Because the white pigments scatter efficiently, you automatically get subsurface scattering. For Barium Sulfate paints, I have read an optimum of >0.5 mm, while the sintered (and hence porous) Spectralon even requires a thickness of 7 mm!

I've tried to read up again. From what I gather, "Lime white" is not actually a pure white but intentionally slightly colored?

I just tried with a recent 2.5 build, and it fails for me too.
