here with the new tool. I did not finished for it still asking for 33hours to go..
for sure it looks more precise with the reflections - see the toilet paper in the glass - (though less crisp than yafarey one)

However you can see light is darker (I tried different paremeters combinatiosn but no improvements..)

Moreover it seem the diffused light are not switced on in the morning (tried 1% and 100% luminosity) while if you set the clock at 1AM they are on and makes the difference.
