You are simply noticing it now, because S4s camera at 13MPx delivers enough details to notice the degradation.
This is exactly right. If you were to take a picture with a lower MP count like an iPhone, then you wouldn't notice it. I have a S4 as my secondary phone and I notice this. But if I put a nice looking photo on my phone that wasn't taken by S4 and upload it to IG, then it looks just fine. It's IG's fault for forcing photos to be cropped anyways which I never understood for a photo sharing app.
