It's not break down of new oil that is the concern on really any decent motor, not withstanding any new car. It's to remove any swarf, any thing that could interfere with rings and bearings. It's not the oil issue, it's the motor cleansing. I will get tons of disagreements...but
Personally, I would change any new motor's oil--if you wish longevity. To run a new motor of any make for upwards of 10K is IMHO, just not wise.
But, to each his own. I just would not wish to buy the car later & thankfully would not have to--but that's me.
