I'm almost positive both of those places use Sharpline Converting digital woodgrain which is printed on 3M high performance film, 3M Di-Noc film is much heavier and is mostly used for architectural applications now.
They don't sell to the public so you have to get it through a sign or graphics outfit.
That woodgrain wagons place just sells overpriced sections off the 8' roll in the approximate lengths needed like the width of the fender or doors. It doesn't work, you need the full lengths to do it right across the doors and to do end matching, lots of waste.
I'm a carpenter/cabinetmaker and have been matching grain for 40 years and know how it's supposed to look when it's done and his way ain't it. I went round and round with that guy, he was a sign guy that got into wagon woodgraining and shows it. I drew up and sent him drawings he requested about applications because he had no clue that Vistas used 9 separate pieces for the sides and doubted me, never heard a word back from the unappreciative jerk after all that, should have billed him.
I found the best price at New Life auto trim in CA, It's drop-shipped from the Sharpline plant located in the Midwest.
