Very little is gained by reducing the MSR below the recomended minimum setting of 0.2.
I draft render at 0.5 and final render at 0.2 when required for a close up.

That said, BB's room looks pretty realistic.

Today we have a very dark afternoon with lots of rainshowers.
It is very dark inside, close to the point of putting the lights on.
