Sky Atmosphere is effecting my sky after switching to Ue5.4

Hello everyone, I just switched to UE5.4. I created a new clean project and migrated one of my Environments from 5.3.2 into this project. When I compare both I can see that the sky and the Horizon looks different, also everythig is a little bit darker and less collorfull (the projectsettings of both projects are the same). This issue seems to be caused by the SkyAtmospere. when I switch it off and compare everything with UE5.3.2 again it matches 1:1. I can see that the SkyAtmosphere in UE5.3.2 only efected the environment itself and had no effect on the skybox but now this has obviosly changed. Would be nice if anyone facing the same issue we could find a workaround for that it was a long journey to find the right look for this environment.

UE5.2.3

UE5.4

I figured out myself. You have to switch on "Holdout " and switch off “Render in Main Pass” in the Advanced section of the Sky Atmosphere then it looks the same again. If someone has the same issue.
