This could be a PCV, but it looks more like a valve stem seal. The reason I say that is you can see the engine starts but the smoke is delayed by about 2 seconds. Then the smoke is thick and dissipates. This indicates that the oil is already in the cylinders or on top of the head. Due to the engine cooling the valve seals constrict and then when you start the engine it pulls the oil in from the top of the head and it burns it off. So I suspect the oil is dripping into the cylinders when the engine is off and so it builds up for the next start.
I would start with pulling the PCV and checking it for oil then replace it just to be sure. The only reason I am not thinking it is the PCV is this seems like a lot of oil for a PCV.
If that is not the issue, then I would replace the valve stem seals and go from there. It is unlikely that it is oil rings due to this being a newer vehicle but clearly that could be the issue. It is just not likely which is why these other options are more likely.
The way to try and confirm this is to use a borescope and look in the cylinder before you start it after it sits to see if any oil has collected in the cylinder.
If not, run the engine in a high vacuum situations when it is cold. Meaning off throttle braking. This means you accelerate pretty hard and then coast with no accelerator and see if there is a buff of blue smoke. You may need someone to follow you for this.
Let me know what you find or what questions you have. Thanks
