Interestingly enough, we had this discussion in the EGY Armed Forces thread with
@Lord Of Gondor (aka LoG lol) about 6 months ago or so since we were trying to determine if the EAF had bought the newer, more modern and longer ranged RVV-SD and not settled for the older and shorter range AE, and we determined the only visible differences between the two missiles is the ends, or the nozzles area. The newer SD has a tapered end, whereas the AE just has a straight nozzle end to it and that really is the only, visible and visual difference between the two otherwise they look identical. Plus it's very difficult to see that tapered end in pics that are of the missile at a certain distance. Once you get to that distance or beyond it, you just can't tell.
This is the RVV-AE with the straight end:

This is the newer and improved RVV-SD with the tapered end:

That's the only visible way to tell the difference and good luck trying to identify the missile in a pic on a flying aircraft! lol Very difficult, but sometime on a high res and close enough like on the tarmac etc., you might be able to catch that end detail and be able to tell the difference.
Saw this today from September 2020 on the tarmac in Ambala, India.
