Greetings,
I know many of us are completionists. I've compiled a list of KNOWN DCUniverse Logo UPC Variants. These are comics with the DCUniverse written in the UPC box. They were typically sold in multi-packs, as far as I know.
They're tough to find in high grade, and there are some that are part of popular collectors sets, such as the Death and Life of Superman, and the Knightsend/Knightquest/Knightfall series.
Here's the known list (at least known to me)
