okay if I got my implementation right - dual quaternion sclerp does take a non-linear path in 3D space
it seems to pick an axis of rotation and a translation along that axis, in order to reach the target state, which arcs it a lot more
lerp+slerp (blue, bottom) vs
sclerp (red, top)

Found the ref to it in this paper - https://arxiv.org/pdf/2303.13395

Some special flavor of slerp?
ScLERP doesn't seem to be a common term, but it's certainly accurate to what it's describing.
