It could be better, but if you want better you’ll pay half what you paid for your gun and wait a year to get an LMT.

Shoot it and get a Toolcraft as a spare/replacement.

I'll never understand why people obsess over things like this.

Not Parkerized , but another type of coating  applied (like dry film) instead.

Hence low down to parkerizing, is that the parts are bead blasted, then hot bathed in either a Zinc ( think colt gray), or Manganese  solution (black) to bond a Phosphate layer on the steel  parts surface that will allow lube absorption to penetrate that surface layer, to prevent the steel from rusting. Hence parkerizing itself, is a dry surface layer, and will absorb lube to prevent rusting.

As for either dry film, parkerizing, or even chrome plated, internal parts on the rifle need to be CLP lubed to help prevent the build of fouling from the gas action.

As for mil spec parts, only applies to M-16 parts, since there are no real specs for Semi auto parts.
Note, parkerizing is a mil spec from the start, and on mil spec's, there is not sealing agent used between the key and carrier, since the spec is to have these parts flat, so they self seal against each other.  Hell key and key bolt wise, there are the older specs, and the newer specs with harder metals, that allow for more torque to be used for the key bolts.

So really, can get hung up on what the finish looks like, or not on parts,  But the real test is if the parts are close enough in tolerances that the B/C will function or not in the rig instead.  
Simply, Pretty is what a brand new rifle looks like if you get one issued to you in Boot camp, while well season is what the rifle will look like by the end of Basic, after you have showered with it/cleaned it over and over a million times to wear the finishes off it (with the few times that you actually live fired it) instead.
