Nissan called the engine all new when the re-design came out in 2016 in the XD. Maybe it was more than just adding DI, they didn't seem know for sure on that Titan forum.
"Brand new" in marketing dept speak only. Same block, valve sizes, bore and stroke - new intake actuation and DI. Evolved or 2nd gen VK56 is likely a better term. VK56DE vs VK56VD UD

They probably share basic architectural hard points but it's possible things like oil pump volume and bearing clearances have been revised.

Do you have a link to any information that would support those suggestions?

Not a bad assertion when you have manufacturing experience. Keeping the block configuration whereas the same expensive machines produce those is a huge savings. Builders can redesign heads, induction, lubricant systems, individual components, VVT, ECM, etc … squeeze it a bit more before making a huge investment in an all new platform. GM Authority walks through changes in engines … would think Nissan has a similar site ?

There is 3rd party evidence to support that assertion. Although this site has been called out for inaccuracy before if one compares the bottom ends look identical. There are a few changes in the piston spec, and the intake valve is a little smaller on the newer engine, exhaust is identical, (guessing to make room for the DI port and they get the same or better flow by altering lift and duration) bore stroke, crank and journal sizes, distances, and diameters are otherwise identical. No need to reinvent the block and spend all that money retooling - HP/TQ is made on top. https://www.engine-specs.net/nissan/vk56de.html https://www.engine-specs.net/nissan/vk56vd.html UD
