ELI5: Why do modern shows like The Big Bang Theory and Two and a Half Men look so bad?

Also How I Met Your Mother. Compared to their contemporaries like The Office or Modern Family. It's not just the props or the number of Cameras and Camera angles, I kind of get that, but the quality of the picture seems much worse as well.

Big Bang Theory and Two and a Half Men are buth multi camera comedies shot in studios in front of a live audience, while Modern Family/ The Office are single camera shows shot on sets or on location.

The difference is lighting. A multi camera show has to have a uniform lighting set up, so they can shoot a scene live in one take cutting between cameras as they go, where a single camera show they set up the lighting for each individual shot.
