Could you get a similar effect by cutting dimples or notches in patterns (like a helical line of small conical holes) along the whole length in a sleeve instead of using separate pieces and infer overall curve shape? Or do the segments need to be cut completely through?

Yes!

The catch is any notch you make will weaken the material significantly and you'll have fatigue failures. That's the sneaky part of using a flexible sleeve, you don't introduce any undesired weaknesses.
