Investigations or apollo levels of quality artwork for the original games simply does not exist and they weren't willing to create it for the occasion. The original trilogy comes of really lazy comparatively speaking.
When it comes to it the linework and artwork for the original games isn't really that hot and looks better on the original system because of both the manual work made after downscaling/manually editing each individual sprite, and downscaling naturally hiding imperfections by nature.
