If so, not exactly aero, they. Compare to the bladed DT Aerolite with 2.0/0.9/2.3mm flat cross-section. So, an aero diameter of only 0.9 mm.



Likewise the bladed Sapin XR



Even the round DT Comp is only 1.8 mm.

If your concern is average speed and going faster, aero is definitely a consideration. Neither the relatively shallow rim nor 2.8 mm spokes can boast of being aero (except in comparison to 48 spoke, box rim wheels).
