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.
