Lost Incredibles 2 Opening "Cast Apology"

I'd be happy to help with this.

For once in my life, lost media I remember seeing! I remember very well, purely because I remember bringing up the 14 years thing to my sister (who did not watch it), and her saying that she hadn’t thought it had been that long.

I remember that all the shots of people talking to the camera had a yellow to red gradient in the background, with the yellow in the center.

I also believe Samuel L. Jackson was there, as the only person I specifically remember was a black man with a hat, and he’s the only black guy important enough to the film to be in the intro thing.

Very shocked this is lost, I’ll have to try and find it later.

On the topic similar to the "Hey swifties" trailers, before Despicable Me 4, there was also a lost trailer where it started out in the style of Despicable Me (it was before DM4), saying "You're here for something Despicable" (possibly the trailer music was Double Life), and then it just cuts to Beetlejuice Beetlejuice.

unfortunately most of the cam footage i’ve found didn’t have anything before… and the one that did was in spanish and only showed the “Bao” short beforehand.

From some private documentation I have, there might have been something like this made for Bee Movie. It probably was around 30 seconds. I'm currently not at my house, so I can't really provide specific details at the moment. 

Now back on topic!
I saw Incredibles 2 back when it was in theaters, and I recall nothing like this, though, my friend does. If this ever popped up on a cam copy/telesync, it probably has to be from the premiere.

if it helps , we saw it in a cinemark in the west within the first few days of its release
