All I can think about is how some of the best and most beautifully shot films ever were shot before the invention of the video assist and without the director looking through the viewfinder as the images were captured. I personally don't think that the technology alone might be the reason for the point you're making. I think it's more about the people shooting it. It's also pretty common for some directors to step away from the video monitors and stand next to the camera to focus on the actor's performances.
This is true, one example that always springs to mind is The Ipcress File which even the DOP had to frame differently to what he saw through the viewfinder because of parallax error. It turned out to be one of the most interesting looking mainstream films ever.
Christopher Nolan never looks through the viewfinder or at monitors but watches the actors during rehearsals & takes. He trusts his DOP completely.
Horses for courses, depending on the context and style of your film.
