What I mean with drama is that the kind of subtleties, the emotional responses, the dialogue, those things are not enhanced with greater FPS, resolutions, or stereoscopic "3D". It's a seriously flat plateau as far bang for buck when it comes to quality in genre. Yeah, you probably don't want to watch an old realmedia video with massive blocking artifacts and muffled sound but once you hit SD resolution and stereo sound, that's enough. Minor jump in enjoyability for DVD quality but then after that is just a waste of storage space, bandwidth, and/or CPU use.
Also, I would say that for any sound, when given quality source files, higher quality sound systems is always better for for anything. You (a rhetorical you) could say that modern, overcompressed and low dynamic range music wouldn't benefit as much and that's probably true. ...but then I'd also say that anything over stereo would be a waste since I only have two ears anyway but whatevs.
Anyway, I feel you're missing the important distinction between emotional connection with viewer and visually immersing the viewer. Just as I don't need to be 1080p with 7.1 surround sound to mourn the death of a character, I don't even need it to be real. It could be CGI, a handdrawn comic, or just a combination of letters on a surface. It's not the number of pixels or how many are flashed at me in a second that regulates the impact it has on me.
