can the windscreen glass in a qr rm 55, which is very murky looking, be replaced with clearer glass like in the bottom screenshot?

That maybe adjustable by replacing the alpha channel associated with the window panes. I can't remember if it's white or black which makes it clear, but a grey-colored alpha would be a percentage of either which makes this a tinted window.
The alpha channel is part of the image (texture) used for the glass.
If no actual image is used, you might not be able to change it without having access to the actual mesh.
