Inglorious Basterds was filmed in 35mm (Fujifilm Eterna-CP Type 3513DI), and FINISHED DIGITALLY. That's to say seen as you seem to know absolutely nothing, all of the post production was finished on a 2K digital intermediate. That intermediate is thus the master for the film, and all that exists on the camera negative is the principle photography itself.
So there will never be a native 4K presentation unless a rebuild is commissioned. Even then all the auxiliary CGI will remain in 2K, and shall be upscaled. But, besides that, Universal are very unlikely to blow $100,000 on the off change of yielding some more spacial detail.
All the relevant colour information exists on the 2K DI master for an HDR anyway.
Stop spreading to misinformation. There is more chance of seeing a bloody unicorn than a mythical native 4K presentation.
Universal lanza 4K nativos de sus titulos de catalogo cuando estos NO estan terminados en 2K. Eso es asi y si no te animo a que me digas un solo titulo, uno solo, donde Universal haya hecho esto.
