TIF to PDF conversion results in high brightness

[tomasr78]

I have noticed that converting TIF files to PDF results in a high brightness-washed outlook. See the example here
test.zip

The code I use is below. Any idea why this happens?

 using (var collection = new MagickImageCollection(Conversion.SourceFile.ToString()))
            {                
                using (var fs = File.Create($@"{Conversion.DestinationLocation}\result.pdf"))
                {
                    collection.Write(fs, MagickFormat.Pdf);
                }
            }

I don't understand why this happens but it looks like this has to do with how the PDF is rendered. When I convert the PDF back to an image I am getting the correct output. Maybe you could ask for more information here: https://github.com/ImageMagick/ImageMagick/discussions?
