Can't get the accurate number of drawn triangles per frame

I’m using Unreal Engine 5.1. I have a scene comprising a grid of objects only (nothing else in the scene, no plane, no sky…). The instanced triangle count of the whole set of objects is about 2.7 million. When I check Drawn Triangles stat (under RHI) in Profiler of Session Frontend, the average of a 10s camera movement through the grid is given to be a mere 625. I think this 625 doesn’t make any sense.

1. so How can I get the accurate number of drawn triangles per frame?

2. and How can I find/compute the average number of drawn triangles for a certain period of time
in Unreal Engine 5.1?
