A solution similar to this question could solve this by using a Stream over the byte array. Then you won't have to fiddle at the byte level. Like this:

Encoding encoding;
using (var stream = new MemoryStream(bytes))
{
    using (var xmlreader = new XmlTextReader(stream))
    {
        xmlreader.MoveToContent();
        encoding = xmlreader.Encoding;
    }
}
