... hopefully no bug of my monitors or my graphics card?
Enscape´s horizon menu offers a "White Ground"-horizon - obviously we have a different interpretation of what WHITE means
or has to look like to deserve this name 
Could you please add a good working one in addition or instead this somehow creamy-dirty one?
The perception of white depends on the exposure. Every surface, even bright snow, will become grey if you underexposure it. Try to increase exposure.
Hi and Thanks ! in any way not white and to simply increase the exposure is not a working solution.
How can I change the background brightness to white without overexposing my scene?
And even at 100% exposure, it's not a white background.
...or much much better would be: I hope that I can soon avoid this horrible horizon line without having
to abandon Enscapes sky at the same time !!!!!!!!!
Another reasonable solution would be to regulate the brightness of the background independently of the used model exposure.
with Auto Exposure
