Scene view looks much better than game view!?

how is that even possible?
U2021.3.1f

 

I couldn't say why exactly without more information, but from a glance it looks like the game view is simply missing ambient lighting information.

 

You're also missing postprocessing effects; obvious is the bloom, chromatic aberration, perhaps tone grading and dof.

 

but why would the scene view look like that? meaning like a postprocessing effect? or how should be the "missing ambient lighting information" restored for game view?

this one has postprocessing

 

okay, checked again. it was a second camera and don't know why I couldn't get the original look
but now opened the project and looks identical.
and the post-processing does indeed show in scene view.
sorry for the confusion.

 

There's also the 'Effects' toggle at the top right of the sceneview (that loooks like two layers with a + sign).
