It can sound sarcastic, but if I'm looking at a beautiful sunset in awe "wunderschön" seems completely fitting
As a reaction to somebody posting a picture I don't think it would come off as sarcastic (without any prior history of one disliking that person)
Depending on the context "hübsch" or something like "omg, wie hübsch" could seem more natural/less uptight/formal
