Well - the ship is painted as Red 5. That means that its "Lukes" X-wing a few days after Rogue one. But even with that I'm pretty sure they are not the same "full size" pieces. The detailing on the top near the butt plate seems very different - even from the blurry images. The Full Size set pieces never match the studio models of the same subject though...
Good Luck.
