XmpData for webp images throws 'Not implemented' exception

When trying to access the XmpData property of a Webp image the code throws a NotImplemented exception.

var img = Aspose.Imaging.Image.Load("image.webp");
var webp = (Aspose.Imaging.FileFormats.Webp.WebPImage)img;
var xmp = webp.XmpData;   \\ Throws exception

Am I doing something wrong or is XmpData on webp images not yet supported?
