Aerosols/pollution in live weather

Go fly from Kathmandu in live weather. It’s METAR is in permanent HZ. And it’s not really haze. It’s pollution.

So it depends on how the IRL weather sources used by Meteoblue are reporting it and if those are part of the data sources used by MSFS.

I flew over Jakarta at FL320 yesterday and the city was covered in a dirty haze. Looked great from the air.

Pollution that affects visibility around airports is absolutely relevant to a realistic flight simulation.
