The proper answer is: "kinda"
Here's the problem:
Is there a standardized heat dissipation rating?
Probably not.
And like all engineering, what is the compromise?
Is it "high end" because of the name? model number? material? shape?
Now add the other components: Calipers, pads, actuators, and levers.
So probably, yes, higher end rotors might dissipate heat better.
Now the question is: will you notice?
If heat dissipation is a primary concern, then I suggest a larger rotor.
More surface area = better heat dissipation.
Consider a system designed for cargo bikes or tandems.
Remember: in the world of engineering, ALL cycling components are low end.
