As has been stated, the comparison pictures you posted are from the model refresh year 2018. This is the last production year of the JK like you have and the second half of the year was the first production year of the new JL model.
Yes, you have a fancy Sahara model. That hood for example is was not on standard Sahara's I believe. As well as the blacked out trim. That center black on your front bumper is silver on a standard Sahara. Wheels are as well. You can see silver accents even on the new JL one.
