No. For starters, I'd have to rerender every images in the previous chapters and post process them, and amount of work is... significant. Secondly, given that I already see severe caching issues before optimization on many of the scenes where I layer up to a dozen or more QHD images (to give me a bit more range for the zoom and pan), at 4K, I'd be increasing those issues a manifold. I doubt we will ever have a 4k version of LomL.
Cheers. Later on, I decided to even that definition go, and they're now undefined by canon. If you have any specific background in mind, the game won't say do do anything to tell you otherwise.
