What if Javik isn't an actual Prothean?

Now I know those who read the title will probably kill me for saying that, but just hear me out: For those who frequently talked to Javik, he will tell you that Protheans would take other races into their empire to the point where they thought of themselves as Protheans. Well, I recently played through ME1 again and found the statues looked wildly different to Javik. It could be that Javik is not an actual Prothean, but instead one of the races subjugated by the Protheans.
