Are Brushes defined in WPF Style Setters instantiated every time the style is used?

Please consider the following xaml fragment:

<Style x:Key="CustomBorderStyle" TargetType="Border">
    <Setter Property="Background">
        <Setter.Value>
            <LinearGradientBrush EndPoint="0,1" StartPoint="0,0">
                <GradientStop Color="#CCC" Offset="0.45"/>
                <GradientStop Color="#444" Offset="0.8"/>
            </LinearGradientBrush>
        </Setter.Value>
    </Setter>
</Style>

Suppose the style is defined in an application-level resource dictionary. When a control references the style, does WPF instantiate a new instance of the LinearGradientBrush class every time? Or is there a single shared instance of LinearGradientBrush that is used?

I would like to know if it would be more efficient to define the LinearGradientBrush elsewhere, and then reference it in the Style as static resource.

There is only one instance of that style and of its constituent objects.
