White text is bolder than black text

[awp-sirius]

Describe the bug

Hello! We noticed that white text looks visually thicker than black text.

I compared the render in Avalonia (top) and WPF (bottom). WPF doesn't have this problem.

Average line color of text in avalonia ui: #9c9c9c, in wpf: #959595 (darker)
RenderOptions.TextRenderingMode="Antialias" does not solve the problem

To Reproduce

Create a new project
<TextBlock Text="FontWeight=500 FontSize=16 FontFamily=Roboto" Foreground="White" FontWeight="500" FontSize="16" FontFamily="Roboto" Background="Black" Padding="20"/>
<TextBlock Text="FontWeight=500 FontSize=16 FontFamily=Roboto" Foreground="Black" FontWeight="500" FontSize="16" FontFamily="Roboto" Background="White" Padding="20"/>
*any font/size/weight

Expected behavior

Visually identical thickness of white and black text is expected

Avalonia version

11.2.1

OS

Windows

Additional context

We only tested it on Windows, but I assume it is also relevant for other operating systems
