I might be wrong, but I believe I've spotted an Air India 787 flying North 12 days ago. Photos taken 10th of April, 11:44z somewhere over Uzbekistan or Kazachstan while cruising around FL330.
What the heck is that aircraft doing there, flying North? I believe they only repositioned their aircraft to Mumbai for parking costs and I would expect an empty ferry flight to fly much higher.
Sorry for the quality; photos taken through cockpit windows and a bit blurry.
