I wouldn't be surprised if the texture of the model in the mod is a photo published by samsung in some way, meaning they would have a copyright on the texture, and publishing a video made with the mod made with the texture would indeed be a legit copyright violation. Keep in mind that in general all gameplay videos are copyright violations because they display copies of textures belonging to video game studios, just…
That's not how copyright works. The forms of intellectual property protection that apply to the Note 7 simply don't apply to a texture in a video game that is video-captured. Even setting aside the broad protections given to parodies (in the US at least.) Whoever made the texture in the mod owns the copyright to that texture. Even assuming it's made from a photo of an actual Note 7, the copyright is still that artist…
Yes, and i'm saying it is possible they didn't make the texture, but downloaded a jpg from Samsung's website and used that directly, in which case Samsung would have a solid and legit case.
The entire rest of your post assumes i had said something else, so i hope you don't mind i skip it.
