It is all subjective and opinionated, but it's a fact that any digital vibrance is adding in something that shouldn't be there. My grandmother likes the setting though, since it makes things stand out to her, same with her TV, has the color setting at 65 and primary colors look like neon signs. If digital vibrance looks like it is enhancing the image on your particular setup you need to first look at your monitor settings, since they are not calibrated correctly. To make up for an uncalibrated monitor you are adding color that ruins the image and gives wrong color values across the board. To each their own though. Ignorance is bliss.
