I think the real issue here is your haze and dust being far to light, while roughness should be lower, and reflection higher on the zebras. You can use lighting settings on the clouds to get them just right. For example, think about the dust, the colour of the dust is going to be fairy dark. It's its diameter of the particulate in the atmosphere catching highlights that makes the whole dust appear brighter.
Check out this quick adjustment. Just to get strong daylight like contrasty lighting on the Zebras, you have to blow out everything else, cause it's far too light already. Darker colours, less density, and adjusted lighting settings could help.
In general when I tend to do haze/dust I try to keep it really light, because in Post you can easily get those saturated areas brighter and adjusted perfectly. For quick post I tend to just adjust levels, curves, and exposure.
