It is a type of distinction recognized by linguistics - https://en.wikipedia.org/wiki/Laminal_consonant - but usually not indicated explicitly or commented on. Secret knowledge, I guess.

The fact that assuming this position necessarily thrusts the tongue very far forward in the mouth explains why the Mandarin palatal consonant series (q/j/x) can only be followed by the front vowels, /i/ or /y/.

If you're interested in learning to produce a foreign sound, I strongly recommend getting recordings (or live examples) to listen to and imitate. Working off a description will never quite get you all the way there.
