Im betting it has copper plugs in it as OE, mopar is famous for being cheap. I cant remember seeing platinum or iridium plugs in any Chrysler product unless some one put them in after the fact. anyway, what difference does it make what plug came from the factory in it, just buy the plugs you like that are correct for it and put them in, don't over think it. as far as the heat that's an across the board thing with mopar also... don't know what to tell you on that

I get that using brand names comes down to a personal preference. For example, I wouldn’t use Bosch plugs in a lawn mower. Those things are just absolute junk. But I have seen where certain brands work better in certain makes: ACDelco works best in GM cars, I’ve always used Champions in my older Mopars, but I’m not familiar with these modern cars at all.
And as far as copper vs platinum, there is a big difference. If you use copper in place of platinum, you’ll burn the plugs up in no time at all because the ignition burns so hot. Platinum might work ok in place of copper, but the ignition isn’t as strong and may not give a hot enough spark.
Haven’t called the dealer about it, but the part store websites only list platinum or iridium, so I can’t see the factory using copper.
