Yeah if the difference is this obvious in a small thumbnail of a heavily compressed image then something probably went wrong. As you said the colours space doesn't look quite right, though I can't identify exactly which mix up took place. I'm also not too sure about comparing it with some unidentified 'streaming' version. That's like comparing a high resolution digital audio file with a phone call. Selective sharpening does have a tendency to overemphasize clear edges while leaving the 'unclear' parts untouched, this can give a bit of a plasticy effect especially on skin.
