I can wear the tech T-shirt, shorts, Headsweats hat, Injinji socks, and $200 Hoka running shoes of an ultra-marathon runner, but I'd still be an old guy who walks 5Ks and 10Ks. But unlike CNN talking heads, I don't pretend to be something I'm not hoping to look cool. What I actually do wear is a mix of what comes to hand (the shirts and shorts) and what is necessary (the hat, blister-resistant socks, and lower-range New Balance shoes). Similarly, podcast viewers don't watch for the stuff on the desk or the knick-knacks of the shelves behind the podcaster they watch and listen for the content. In my case, I find Jon Parshall's tropical shirts and the 1980s floral wallpaper behind him when he does the "Unauthorized History of the Pacific War Podcast" mildly amusing (Seth Paridon's office is more business-boring), but I listen every week for the content.
Whether standing behind some sort of speaker's podium or seated at a kitsch-filled desk, Anderson Cooper's content is still Anderson Cooper's content. If people are declining to watch/listen to him, the packaging won't change what people choose.
