Well you got me. I haven't watched broadcast TV for decades. I do see that phenomenon a lot with vloggers at present.
Am I also incorrect that they appear not to be looking directly at the camera? Looking back after your comment I still think it feels like they aren't.
The AI characters? Nothing about them feels right. The audio looks out of sync with the fake lip flaps. The dude's arm gestures are horrendous. It's AI/cgi, yet the fake background looks like a bad chromakey. You already pointed out some of the audio/voice issues.

I genuinely wonder if that's intentional. Maybe that looks more "realistic", and gives the audience something to stumble over that's not other AI artefacts?
The result to me looked more like a Zoom background replacement rather than a weather chromakey. That's what really looked bad to me. Even the full studio chromakey looks much better where the anchors are at a desk in front of a color vs a full studio.
