As far as I understand, the pigment <1,1,1> is the pigment of the floor,
while the emission 1 pertains to the HDR background. Which of course
isn't all-white everywhere.

Not in 3.70; we'll probably need negative color components when we go
for proper color profile handling, so it doesn't make much sense to just
toy around with how they're handled just for the fun. If we want color
profile handling to work properly, we need to spend some serious
thoughts on color math.

Thank you for your answers. When I increase emission a have more bright colors,
than I need, and when I increase defuse shadows on the floor are to fade((
