Could ultraviolet digital copy codes still be redeemed?

Hey guys! Do ultraviolet codes still work? I am tempted to buy the Laika collection from Walmart (the only version that had a digital copy with all 4 movies) for $28 but I can get it without digital on Amazon for $19.

The thing is I heard ultraviolet may not work anymore as it’s been closed for years.

But then I heard that vudu (aka fandango at home) can still use those older ultraviolet codes. But then don’t want to spend the extra money if the code won’t work.

There’s conflicting info online on if it’ll work or not.

Does anyone know if it would?
