mmm....the higher the KV the more hot it gets. As @Jerry-rigged notes, i have never seen anything that says the manufactures are changing the construction of the motor in some way to dissipate that heat better or utilize components that can handle it more as they up the KV. The charts tell you the motor is going to draw more (which will result in greater heat) but i don't think they are telling you it will take more. In RC you don't "KV up" to reduce heat...you "KV down". Think i just made up some terms thereThe higher the KV the higher AMP load the motor can take and the less hot it gets.
