Sky through window issue

Guys this is a pretty newb question, but I’d appreciate some help with.

In my room I’m trying to generate a sunny view from the window as you enter the room.

Now from close up when you look through the window it looks OK:

But as you enter the room the view from the window at a distance is almost completely white:

I’d like a lot more blue sky in it or at least for it to look like the first image above.

I’ve tried physically shifting the skysphere lower in the world it does nothing, there must be a setting I need to mess with but what and where?
