Well the pic may just be casting shadows on the eyes but true percs also tend to have a more rounded dorsal. False percs tend to look more like what you have frog ... looks a bit more like a mohawk. The middle bar on false percs are usually more sideways triangle like yours, while they tend to vary a lot in pattern and this is by no way a means to tell, all things combine, your fish looks like a very classic occelaris.
