Let me get this straight, is there any friggin' way to disable the Tonemapper?
I tried just about everything
I asked in previous threads like this one:

And got no answer on how to replace it.

So please, pretty please, with sugar on top, who do I have to beg at Epic Games, to implement a checkbox in Post Process Volume, or something like that, which was promised years ago.
Is it really that difficult?
You can get sooooo close to the look that is unaffected by the Tonemapper by tweaking a Post Process Volume:

But can you disable it completely? Nope! Not in game, only in editor window for some unreason.
