In my case
original scene, perspective camera, no assumed gamma -> 1.PNG
original scene, spherical camera, no assumed gama -> 2.PNG
new scene, perspective camera, 2.PNG as sky, no assumed gamma -> 3.PNG
new scene, perspective camera, 2.PNG as sky, assumed gamma 1.0 -> 4.PNG
new scene, perspective camera, 2.PNG as sky, assumed gamma 2.2 -> 5.PNG
1.PNG = 3.PNG
1.PNG != 4.PNG
1.PNG != 5.PNG
I compare image when POV-Ray displays it. Not with other software.
