Are shadows supposed to be this dark in certain places?

[Lemnus28]

I use ELFX Shadows, cranking up the brightness and gamma does nothing to the shadows. Not even changing Nivida color settings or my monitor settings does anything.
It seems like it only affects dark colors the most by making them all a solid black void. It only is an issue at certain times of the night and at dawn. I'm also using the GTS collection
and when I was messing with ELFX Shadows it broke somethings which gave me a ctd but I fixed the ctd by disabling an esp that wasn't previously an issue, so disabling ELFX shadows is gonna cause problems because GTS patches for it.

So really I just want to know if this is just the way its supposed to be, and if not-a solution. Thanks.

I have no idea what ELFX Shadows is, but in my humble opinion, those "shadows" don't look natural. Whatever is causing that (ELFX Shadows, perhaps?) looks like it's just cranking up the contrast rather than enhancing shadows.

p.s. I don't use ENBs nor reshade. Sometimes (rarely) I use Nvidia Game Filter if I want special effects for a film, but other than that I only use in-game engine lighting and mods which change image spaces and image space adapters (the method the engine uses for controlling lighting).
