Texture2D.LoadImage unable to parse bytes

I'm downloading a raw byte array to be used as a Texture2D using a technique by at SO.

 UnityWebRequest www = UnityWebRequest.Get("myurl");
 
 DownloadHandler handle = www.downloadHandler;
 
 yield return www.Send();
 
 if (www.isNetworkError)
 {
 
     UnityEngine.Debug.Log("Error while Receiving: " + www.error);
 }
 else
 {
     UnityEngine.Debug.Log("Success");
 
     Texture2D texture2d = new Texture2D(8, 8);
 
     texture2d.LoadImage(handle.data);
                     
 }

LoadImage, however, can't parse the byte array and gives me 'red question mark' fallback.
