GI in WebGL preview (Unity5.1.0) supported yet?

I wonder weather GI is actually supported in Unity5.1.0 yet?

For hours I’m doing tests with WebGL. But the results in the browser (Safari) look very different than in the Editor. With a Light set to Realtime the lighting is very different. And with a Light set to Baked the texture is much poorer (eg. no AO).

WebGL is in Preview Status and Runtime Gi is not supported yet.
