Thanks, everyone, for the ideas. Finally have some down time and did some more digging and pondering and I think I finally found an easy, and make it look similar to new, answer.
I dunno if they only recently added it, or if I didn't notice it when bought the spare seam tape from trekwood for the walls, but trekwood now has 24" wide seam tape in the same wood finish that was used for the wrap on the wood (holms maple)

If a person looks close at inside of the shelf (along inside edges) they might be able to figure out that it was redone, but it'll look a whole lot better than it does now.
I might end up taking it down from the wall like you suggested JRTJH because it does seem that it'll be easier to do a good job on the repair (a pain to take down and put back up, but..)
This will also sort out another issue that has been annoying me - there's a small, removable board under fridge covered with the holms maple wrap where they did a really crappy job cutting the board. It looks like what you'd get if you used a table saw with slightly bent shaft and a really dull blade. And, it was cut too small to boot. A spare scrap of wood from the shop, slap on a piece of seam tape, and that'll end up looking better than new. It's not a huge deal, because it's down low by the floor and nobody sees it unless they get down low or are sitting in dinette and look over and downward, but it's just been bugging me, you know? I guess it's my father's fault. He was OCD about work being done right the first time and could, at a glance, spot flaws in workmanship that most people wouldn't ever notice. I'm not as bad as he was, but. . .
Thanks again for all the input and tossing around of ideas, everyone. I do appreciate it. Now to get some of that ordered while it's still available
