Baked Lightmap preview result is very different from the baked one

When using the Baked Lightmap visualization mode, we can switch between a preview state (auto replacement) and a baked state (Lightbaker output from the previous on-demand bake)
This preview state result is very different from the baked state (see image below) : different exposure ? different colors ?

Reproduceable with the URP template scene :
Project : URP Template
Project Scene : Garden
Project Branch : main
Project Commit : Merge pull request #19 

• Open the _Garden _scene
• Place the scene camera inside one of the interior rooms
• Bake using the GardenDraftLightingSettings
• Use the Baked Lightmap Visualization mode
• Set _Preview _for the Lighting Data, and wait for the preview to be computed
• Switch to _Baked _for the Lighting Data
• See the difference between the two

Also reproduceable with a simple scene :

• Create a new scene
• Create a few cubes, set them as 'static' and using 'Lightmaps'
• Bake the Lighting
• Use the Baked Lightmap Visualization mode
• Set _Preview _for the Lighting Data
• Switch to _Baked _for the Lighting Data
• See the difference between the two

Note :
With this version of the editor, when baking on demand this error happens :
_StackOverflowException: The requested operation caused a stack overflow.
UnityEngine.Rendering.ProbeVolumeLightingTab.PrepareAPVBake () (at ./Library/PackageCache/com.unity.render-pipelines.core@16.0.2/Editor/Lighting/ProbeVolume/ProbeVolumeLightingTab.cs:939)_
It's know and linked to APV

Another error happens when using the preview state :
_FileSystemError code %i after call to FileSystemEntry::LastModified() _
