seeing sky color reserialization diff on scene file when changing something in scene hierarchy:
- m_IndirectSpecularColor: {r: 0.12715052, g: 0.24939102, b: 0.35011643, a: 1}
+ m_IndirectSpecularColor: {r: 0.12720121, g: 0.2493818, b: 0.34966052, a: 1}

no physical based sky, just a material with a Skybox/Panoramic shader and a 360 lat-lon layout image

I am reproducing the issue by having two scenes loaded in the hierarchy, and depending the active scene, when I hit play/stop the active scene m_IndirectSpecularColor is being automatically modified by unity, it makes sense when the active scene is the one with lighting stuff configured but when the active scene is the other one it makes no sense to modify that serialized value.
