Yeah, as I said the spine layout is the same aside for the UHD logo being a Blu-ray logo, and it’s not brown but colorful. The interior matches across all three SteelBooks (this new one, lenti magnet, and original red pigment) so you can swap covers/spines and the interior won’t be messed up at all. That’s all I was pointing out. The red pigment SteelBook also has the same helmet on the back but again in red, so that might be an even better “matching” design to swap in if you really hate the brown.
I don’t, I’ll be selling all my copies of these movies anyway after getting the new matching UHD sets. Don’t need 3D, and the discs in these SteelBooks all have disc art for the first time. Pretty much all I could ask for.
