With filter at 1 on the sky_sphere and NO background, with beta 39, I
got the attached pictures.

sky_sphere {
 pigment {
  gradient y
  color_map {
   [0.0 rgbf<0.33, 0, 0.528, 1>]
   [1.0 rgbf<0.481, 0.774, 0.645, 1>]
  }
 }
}
global_settings {
 max_trace_level 7
 ambient_light rgb<0, 0, 0>
}

 //  background { rgbt <1,1,1,0.5>}
