I called Sony pro and to my pleasant surprise the advisor was quite knowledgeable and explained that the behavior very well. He has observed it himself. It is likely to coming from a 2nd proximity sensor that is fitted behind the main LCD. The idea is to prevent the shadow of your body activating the EVF when shooting at hip level. When shooting with the 600 f/4 hand held the user is likely to put the camera and lens facing down periodically which would activate the rear LCD proximity sensor and shot off the EVF. When picking up the camera with the sun behind you the EVF sensor is saturated so the camera relies to proximity sensor to activate EVF but this sensor is not very accurate and may not work all the time. This happens even if you set display to EVF only. (EVF will still turn off when you lower the camera)
The solution is to use a piece of tap to cover the eye sensor. The EVF will never turn off and the proximity sensor will not engage.
Not the most elegant solution but it should avoid missing the shot. Battery usage will increase and you have to remember to take the tape off at the end of the shoot
Thanks all the sensor is clean has nothing to do with cleanness.

Wish I had called them earlier
Hope this helps
