PCCB - do they need to be bedded-in?
This will be my first car with PCCBs. I usually bed in my steel rotor brakes when I get my cars. Is there any specific procedure needed with PCCBs or are they good to go right from the start?

For maximum performance and so as not to experience pad fade your first time on a road course, you should follow a specific break-in procedure. On the street it is not generally an issue.

My understanding is that CCB mainly rely on transfer friction, so doing a proper bedding in procedure to lay a nice pad transfer layer on the rotors will ensure optimal performance. If the brakes are not used hard regularly, repeating the bedding procedure at regular intervals (when the transfer layer is gone) will ensure maintaining that maximum performance.

The PCCBs come bedded in from the factory.
But, like others have mentioned, depending on your use, they may need to be re-bedded in.

I drove my TTS on the road a bunch then went on the track. I didn't "bed in the brakes". They work amazing!

Do you find any mention of bedding in the brakes?
You would think that if it is necessary the manual would mention it.
You don’t need to bed in the Porsche brakes.
You can, but not necessary.
The OEM pads are not aggressive enough to require bedding-in, and in fact are cured/bedded-in at the factory.
And the slightly dull finish on the rotors are not a sign that the brakes have not been bedded in. It's often just rust, which will easily come off after a few stops.

Interesting, my speedster when new I got a dash message said bed the brakes several times. Didn’t look in the manual, but the message was clear it needed to happen.

Have you read the 992 911 manual?

i think there’s a big difference between bedding in being a specific requirement in/not in the manual and the suggestion it’s done at the factory. I very much doubt it’s done at the factory or as part of manufacture. On new discs or pads that are box-fresh (so not rusted), whether pccb or iron, it’s possible to see the finish is different to when they’re used. Definitely not bedded in from the manufacturer or porsche.

I've actually seen the menu options on the 991 with a PIWIS II tool and don't recall seeing such a message in the various fields.
Wish you had taken a pic.

Ive searched and can’t find damn, it only occurred on my Speedster and not my other GT cars. I called the tech went I got it, and he told me the procedure to bed the brakes. It was a yellow message and I got it like 4 times, and it’s not in the manual to your point.
