Could the noise be the direct injection from the top end just sounding different from the bottom side?
That doesnt sound like a rod knock to me. A rod knock produces a very deep hard knocking sound. Not sure what that noise is but I don't think it is a rod knock. Also if you had a rod knock you would have a ton of wear metals in the oil.
That's the exact same sound my reel mower makes when I have the bed knife adjusted too close the blade.
The wear metals in this UOA don't indicate a failing bearing, although iron, aluminum and copper look high for the short miles run, but this may simply be characteristic of this engine.
Maybe a trip to the Porsche dealer is in order?
This new noise obviously came from somewhere, the car is under warranty and you should expect better than decent customer service on a car the price of this one.
Even if you do have a failing rod bearing, that's something for the service folks to determine and remedy.

the prominent sound looks more like being originated on a power-steering pump or "some sort" of air-pump,
airpumps are something that seems to me being more common these days on modern engines, namely more on diesels... because they don't have natural vaccum on the intake manifold

Hard to tell from the video but it sounds like an accessory on the front of the engine is going.

Many German cars still use an exhaust air pump to lower cold start emissions. This may be the noise he is searching for. Modern exhaust air pumps are operated by electric motors.
That in mind, OBDII is supposed to determine if the air pump is functioning properly. I don't know if air pump problems are happening to you. That in mind, a pump could develop noise before it stops functioning correctly.
