I found the pic I was looking for for this one!
Yes, it is. Usually it is just the totally 'nude' and natural vegetable tanned leather (hence the name Vache Végétal Naturel), that we all know and love. When new, it is porous and more matte, and with time it develops a darker colour and a beautiful sheen, the lovely patina

For a few models they pre-tan the VVN, so the patina process gets a jumpstart and the bag won't be as sensitive. The Diane, the Odéon and the Boîte Chapeau are such models with this 'aged' VVN, as they call it.
If you look at your VVN items from up close, you can easily see the pores, if you have items that have an ample amount of VVN (like the bottom of the Alma or the Noé), then you can also see veins and natural variations in colour and texture. VVN is not a uniform material, it is truly natural and beautiful.
VVN is always full grain leather, there a few reasons why:
- Prestige: they are not H&M, using anything but the best would damage the brand. No matter how they would try to hide, it would come out. Just remember what Apple had with the Chinese factories. They tried to hide it as much as possible, they tried to act as if they provided great working conditions, and it still came out, everybody knows, and it is a PR disaster for them.
- Hard to hide: if the topmost layer would be sanded off to hide the imperfections (that is how top grain and lesser quality leathers are produced), the leather would instantly lose its natural finish, it would need some kind of treatment and coating. Simply just touching or looking at the leather tells that is hasn't received any. No thick paint.
- Heritage: their trunk makers used these best leathers a 100 years ago too. They might innovate, but that cannot mean compromise, since that would also end in a PR disaster, if they spat in the face of the ancestors. A Vuitton bag cannot be made with Michael Kors leather.
- Quality: full grain hides are the strongest. No wonder why a Vuitton bag last 10-15 years even with careless and heavy use. With care, they last for decades and decades. Leathers with inferior quality would last way less, no matter what extra tricks they'd use to reinforce them.
- Availablity: they only use full grain simply because they can, not a big deal. Quality cowhide is not a rare material, it is just not cheap. But when you sell bags for thousands, you can easily justify the hundreds for a single VVN hide.
They used this photo on the website under the Savoir Faire section, years ago. It is absolutely beautiful, and you all can see the super thick topmost layer, and how it transitions into the less dense fibers of the layers below. This is a noble material.
