I am arguing that they're invaluable even if they're not needed now that LCD technology has advanced in terms of being able to assemble it.

It actually doesn't matter if its a screen, artwork or a photo. IMO bordered (black or white) photos is vastly superior to borderless photos. There is a reason why every museum that displays fine art photography have borders, almost always.

I don't see any distinction with screens. Perhaps, even more so important to have distraction free edges on monitors than photos.
