Alright, so get this: if I try and change the brightness settings in the Nvidia control panel, after moving the slider to darker or lighter, the screen will immediately adjust back to a standard brightness. This happens in games too. I'll find an area too dark and change the in game brightness and bam, it just reverts back. The thing is, the slider doesn't jump back or anything, the computer just adapts the new brightness so that it looks like the standard. Here are a couple of screenshots to visualize my rambling. Notice the gamma settings and the fact that regardless of which setting I chose, the screenshot brightness is literally exactly the same. This is not a monitor issue because 1) I've turned off all adaptive measures on my TV and 2) those are screenshots, they would not display the monitor settings.

Edit: here's some Windows Calibration screenshots. Notice the slider positions and the fact that the image doesn't change relative to the slider.

The brightness is absurdly high and it's killing me. I pledge my allegiance to this website and will dedicate my abundant debugging experience if anyone can cure this insanity.

Oh my god, I don't know if anyone will see this, but this guy mentioned f.lux, and that was the problem!
Even though it was in "disabled" mode, you have to completely close that program.
Then adjust your color and gamma settings.  You'll notice instantly that the problem is gone!
I love when things like this are solved :)
