From my testing, the EVF is more colour accurate than the back screen - I used an i1 Display Pro colorimeter to measure the colour temperature of the back screen in its default factory setting and the result is ~5750K, quite a deviation from standard D65 white point. Go to the LCD screen setting and push the "B" to +2 gets it to ~6400K region with a DeltaE of about 1.3
The EVF has a slightly higher colour temp of ~6900K, adjust the EVF setting "B" to -1.
