Rflections is too bright, how to fix?

Why reflections is too bright? I did read that reflection capture are normalized by most bright point it sees, but really cant understand what exactly I should do with that.
I can’t just lower brightness of reflection capture. In this case dark areas became too dark.
My reflection capture is right in size of the room. And Skybox is actually a SkySphereBluprint from standart assets.
Sky Light is set to capture scene, has 150000.0 threshold and Intensity of 3.
On screenshot you can clearly see transition and difference between screen space reflection and cubemap.

BTW Why even normalize? Aren’t they should be HDR?
