Why do mobile particle shaders look bad in game view but not in scene view?

I used the explosion from standard assets for a grenade, which looks just fine in the scene view. The smoke particles however look like black semi-transparent squares in the game view. This is an issue with the mobile shader as I’ve figured out (mobile/particle/multiply) but now my question is why?
I.e. why does this shader look fine in the scene view but not game view, does the scene view implicitly utilize other shaders? Or is it something else…

This insight would be really valuable, thanks in advance!

As said the explosion is from standard assets, it’s located here: StandardAssets/ParticleSystems/Prefabs/Explosion.prefab

Mybe because you can’t see it in the scene view, because grey on grey?
