I really liked this presentation of the film, but since you asked, here's the one issue I noticed:
Some of the shots in the Matrix during Cypher's betrayal scene have minor banding. It's not that big of a deal, but it becomes really noticeable in the two close-ups of Trinity at 1:30, watch the shadow on her face.
There may be other issues, but when I watched the film it was for entertainment purposes and not quality control.
