I am not sure I truly understand what these specs mean for a laptop LCD matrix:
- Wide color gamut
- White variation
- "Haze" 44%
Which values are better when picking a screen?

Here is a simplified explanation of each specification and their effect:
Wide Color Gamut (WCG): This simply is a qualitative measure of the number of colors the LCD display can use as opposed to the standard Rec.709 gamut. This generally means more vibrant colors, as opposed to a standard display. This is because:
You should use a LCD display with a WCG for a better picture and color fidelity. If this isn't necessary then go for a standard Rec.709 gamut.
Thus, a higher white variation means difference in the white brightness in individual spots of a fixed viewing angle. This should be the lowest possible for visual accuracy.
Haze: This refers to Reflective Haze. Haze is the measure of how much reflections are diffused. A higher haze rating usually means an anti-glare coating which is increasingly matte. This generally makes colors less pop out, but with a decrease in reflections. Here is a comparison picture of different levels of haze and the effects on reflections and color:
Generally, under high ambient light, a higher haze is better for increased readability and visual acuity. If there is little chance of reflections or no ambient light is needed, then the haze percentage doesn't need a higher than 25%, which increases apparent color accuracy.
