Vernier gauge taking spot measurements around the clamp's internal circumference.
If they're not all the same (give or take a smidge), it isn't round.
The same goes for checking the seatpost itself for roundness.
ETA - I'm not 100% certain that I've understood your question correctly. -
Is there any way of easily telling
Yes, ask the manufacturer. Responsible ones will already have marked the differentiating parts with the rail size they fit 🙂
For designs which don't work with both 7mm round and 7×9 oval rails, it should be pretty obvious at assembly whether your rails match your clamp.
What torque did you use once you'd decided the manufacturer didn't know what they were talking about? What the thread size of the fastener?

Is there any way of easily telling whether a seatpost clamp is for round/oval/other(?!) saddle rails?
My seatpost is a Neil Pryde cf jobbie from ebay and my go to saddle ended up wiggling free mid-ride.
I can't work out why, other than me being scared to torque up to the required 15nm (because it literally sounded like a lot - huge creaks). Could it be rail profile?
This is a very novice question, I appreciate!
