I would vote for option 5: black level.
Black level is the canvas onto which the display paints all it's colors. What's the use of an expanded color gamut if piss-poor blacks are washing out all the colors? What's the use of high dynamic range if the display can't create a convincing shade of black? What's the use of a higher frame rate if the display's inability to create a realistic sense of contrast takes you out of the movie anyway? This is the reason OLED continues to garner rave reviews despite it's high price and litany of issues.
What to do if you find yourself stuck with no hope of rescue:
Consider yourself lucky that life has been good to you so far. Alternatively, if life hasn't been good to you so far, which given your present circumstances seems to be more likely, consider yourself lucky that it won't be troubling you much longer...
