Replicating detail lighting view

The detail lighting view mode in the editor makes for a nice look that would work well with archviz projects. Unfortunately, there doesn’t seem to be a way to turn it on in the packaged game (trying to force it on with blueprint and console command doesn’t work). So I’ve been trying to replicate the overall look.

The description of the view mode says it just applies a basic white material that makes use of the normal maps, roughness and emissive of the original material. However, when I apply a basic white material to all my meshes the scene still looks a lot different to the detail lighting mode. Does anyone know anything about what detail lighting actually does to the overall rendering of the scene and if it’s possible to replicate?
