ToGdiPlusBitmap - colour profile preservation

When using ToGdiPlusBitmap, is there a way to preserve the colour profile in the same way that GDI+ itself does when you load an image and pass the appropriate parameter:
public static Image FromStream(
Stream stream,
bool useEmbeddedColorManagement
)
If I use GraphicsMill to load the image (ImageReader.Create) then use ToGdiPlusBitmap(), the colours in the image look incorrect (or at least different!) when compared to the same image loaded using Image.FromStream with the useEmbeddedColorManagement parameyter set to true.
Is there any way round this?
Thanks!

The colors are displayed incorrectly when an image has non-sRGB color space. So the easiest way to fix the problem is to convert an image to sRGB. Code:var gmBitmap = new Aurigma.GraphicsMill.Bitmap("../../../Copenhagen_RGB.jpg");
gmBitmap.ColorManagement.DestinationProfile = Aurigma.GraphicsMill.ColorProfile.FromSrgb();
gmBitmap.ColorManagement.Convert(gmBitmap.PixelFormat.HasAlpha ?
Aurigma.GraphicsMill.PixelFormat.Format32bppArgb : Aurigma.GraphicsMill.PixelFormat.Format24bppRgb);
var sdBitmap = gmBitmap.ToGdiPlusBitmap();
pictureBox1.Image = sdBitmap;
