At work I inherited a raytracer codebase with a severe memory bloat problem on terrains. The size of terrain BLASes is precisely what one would expect from a bog-standard BVH with branch factor 2, so I'm sure you're right. This is on Turing. Nvidia would've been motivated to de-risk the introduction of RTX by making boring choices. You may well see different results on later archs.
