Need someone who is good at Identifying Water Monitors

I have an Asian water monitor, and I'm just curious as to which breed of water monitor he is (IE: Asian Water Monitor: Varanus salvator salvator, Andaman Islands Water Monitor: Varanus salvator andamanensis, Two-striped Water Monitor: Varanus salvator bivittatus, Black Water Monitor: Varanus salvator komaini or Southeast Asian Water Monitor: Varanus salvator macromaculatus)

I'm just curious, I'm not planning on breeding or anything. I love him irregardless of what breed he is. I'm just curious. So don't bother posting comments about how it doesn't matter, etc...

Here's some recent photos of him:









If you need different views of the head or other views, just tell me, and I'll get them.

Thanks

what you have is a sumatran water monitor, I have 5 of my own and they are breeding as of now

Thank you!
