Not exactly. "Wie geht's"? is more informal and it is perfectly acceptable to say something like "ja muss" or "geht so". There is no forced positivity. You can imply that you are feeling bad or just normal without it being a big deal.

Plus "Wie geht's" is more impersonal. It is more like asking "How is the situation?". It is not as direct as asking "How are YOU" (with you being the subject of the sentence instead your mood/situation being the subject) which feels much more intimate when directly translated to German.
