You might be right in your assumption. I've watched Tata Steel 2021 live with Peter Leko (ex WC challenger btw) and Tanya Sachdev analysing the games live without computer assistance (except eval bar sometimes but no lines) and then watched Gotham's recap the next day. The difference was obvious with Levy missing the most interesting variations and positions in the game, which is funny because he probably uses engines for these analysis videos.
