To interpret “Yuck!” as “That is bad/yucky” is to turn what is ostensibly an expression of subjective experience into an ostensibly “objective” statement. You may as well keep it subjective and interpret it as “I am experiencing revulsion.” But you’d have to be a pretty cunning arguer to get into a debate about whether another person is really having a subjective experience of revulsion!
It’s both—expressing revulsion has a normative component, and so does even experiencing revulsion.
To illustrate: If I eat something and exclaim, “Oishii!”, that not only expresses that I am “experiencing deliciousness”, but also that the thing I’m tasting “is delicious”—my wife can try it out with the expectation that when she eats it she will also “experience deliciousness”. It is a good-tasting thing.

It still sounds just like two people experiencing subjective deliciousness. What if a third person, or a dog, or Clippy, finds it not so delicious?
