Well, you can count the supralabials and the infralabials, and you can identify the scale rows the lateral stripe is in.
You can even tell that the dorsal stripe has a very different colour than the lateral stripes. I did a bit of editing on my computer changing the contrast settings and even some black markings below the lateral stripe became visible. I don't see any red on it, though. It's a poor quality picture, apparently taken with a phone and not a camera.
What you can't count are teeth, total number of scale rows and subcaudal scales.
None of these eliminate the possibility that it's a hybrid, of course.
