Yes, take some better pics, especially of the head and mouth.
The mouths of zebra's and peacocks are so differently structured that if this fish is one or the other the mouth shape alone will be the discerning factor. To my eyes, photo #2 clearly portrays classic metriclima/zebra-complex mouth structure. Also, body-form too mbuna-like to be OB peacock (even though OB peacocks are peacock x mbuna hybrids).
