Can I ask how you came to that conclusion?
Face shape, location of the eyes from tip of snout and head shape. Also the shape of the lower jaw. And especially the view from the top easily differentiates Argus from Striata.
Striata has a wider U shaped head while Argus is narrow.
(The platinum Argus of the member Inter below is possibly a female although I could be wrong. I've seen one with a wider head while retaining the narrow shape.
From what I've read a male Argus is larger, head has a prominent downward curve with a longer snout, not to mention wider. The Platinum Argus of the member Sacrosuchus is possibly a male.
The platinum Argus in the video above by OP is possibly a female. Although from what I've read Argus reaches sexual maturity at about 12 inches. So it's too early to tell.)
So you see the top view and the difference is obvious. I call it the difference between the cobra and the python head.

Argus also has a more prominent lower jaw compared to Striata. Thicker with a more upward curve.

Striata has a more frog like face similar to Emperor with eyes typically located closer to shout unlike Argus.

Finally let's not forget the teeth. The whole set profile, shape, size and location. Striata has teeth similar to Emperor Snakehead with sharp ones are small and located at the sides and really nothing much in the front or middle jaw. They are also mostly located or perhaps more visible in the lower jaw.
Argus however has killer set of teeth. Once you see the single sharp tooth located in the center of the upper jaw you can pretty much know what it is.
