WriteableBitmapConverter Bitmap STATISTICS changed

[imsulag]

Summary of your issue

i planning to Load 16bpp grayscale bitmap on windows. i successfully change mat to WriteableBitmap by using WriteableBitmapConverter method. But when i check between on original and saved bitmap in QGIS, something changed in STATISTICS.

Something changed in STATISTICS. could you explain reason, and what i have to do to fix this situation.

Environment

Write your environment.

What did you do when you faced the problem?

Write here

Example code:

string fileName = $"C:\\Users\\User\\Desktop\\grayscale\\C1_20240611014916_17892_00672307_L2G_R.tif"; // grayscale

Mat src = new Mat(fileName, ImreadModes.Unchanged); 

WriteableBitmap bmp = OpenCvSharp.WpfExtensions.WriteableBitmapConverter.ToWriteableBitmap(src);

SaveBitmap(bmp, $"C:\\Users\\User\\Desktop\\C#Study\\aaa\\test1.jpg");

Output:

here is original

![original](https://github.com/user-attachments/assets/064ee89b-da96-48c1-9dd5-5582cea8e671)

and that is Converted WriteableBitmap. i saved it by JPG.
