At least right now, 4k83 is still a bit lacking in the color correction department, so if you’re looking for “that projection print look” this one can look better in that regard. But yeah, I get where you’re coming from. Color aside, 4k83 is the Cadillac of projection print preservations. This is kindof a VW Microbus with an awesome paint job. It may not be king of the road but it’s still pretty nice.
But also there’s just people who like to have all the versions, or who want to compare and judge for themselves.
