Greetings,
This is an interesting question. One might expect to see a v1 or v2 card if they had different memory types. Not seeing that.
Since there does not appear to be a way to discern, I would recommend reaching out to support.
Also, please note. Flashing for the sake of having the "latest" is not necessary. If your card is performing as expected and you are not experiencing any issues, I wouldn't flash. Reach out to support and see what they say. Then you can make a decision.
Appreciate it if you would post a follow up as this might help others.
