couch material setting seems me not good, it's not real.

 

Use BBlightmeter and make sure you don't let it show yellow or red.

The picture with 85% light intensity on the direct light looks great with the envsphere set at 1.0 ...

The 150% intensity is simulating another planet where its sun burns brighter than that of the sun orbiting the earth.
