Why would that be? Eg Organs are warmer than hands etc - there certainly is a gradient. The heat from metabolic processes will not become obvious immediately because it’s redistributed before it’s lost to the environment.

in warmblooded animals core temperature is homeostatically regulated to high precision, preventing the kind of heat storage you're talking about
