Theme based images

Is your feature request related to a problem? Please describe

I have a company logo that is not visible using the dark theme. Is it possible to change the image based on which theme is used?

Describe the solution you'd like

Ideal usage would be something like...
<Image Style="{ThemedResource CompanyLogo}" Width="200" HorizontalAlignment="Center" RenderOptions.BitmapScalingMode="HighQuality"/>

Describe alternatives you've considered

I have tried implementing something using resource dictionaries, but I wasn't able to get it to work.

<ResourceDictionary.MergedDictionaries>
          <ui:ThemesDictionary Theme="Light" >
              <ResourceDictionary x:Key="Light">
                  <Style x:Key="CompanyLogo" TargetType="Image">
                      <Setter Property="Source" Value="/Assets/CompanyLogo_Blue.png"/>
                  </Style>
              </ResourceDictionary>
              <ResourceDictionary x:Key="Dark">
                  <Style x:Key="CompanyLogo" TargetType="Image">
                      <Setter Property="Source" Value="/Assets/CompanyLogo_White.png"/>
                  </Style>
              </ResourceDictionary>
          </ui:ThemesDictionary>
          <ui:ControlsDictionary />
</ResourceDictionary.MergedDictionaries>

Additional context

No response

The issue provides no file or test references. Start by locating WPF UI theme and resource-dictionary handling, then determine how theme changes could select different image resources. Done means the requested light/dark image scenario works and is covered by an appropriate test or example.
