Yes, it boils down to a look that you can’t create with a computer, you can but some directors or directors of photography just want a certain look - not for entire films mind you but say the film requires that “camcorder” look for a scene where an actor is watching a home movie, they’ll use a MiniDV camera to achieve that look. And/or a lot of documentary footage for a “making of” or a documentary itself will use multiple cameras and they might incorporate a MiniDV just to give that extra look to it.
