Right from the outset, the textures were stated as being an alternate set of textures. It's just like the high res textures in jHeretic are not exact dupilcates of the originals, but versions that keep the atmosphere and general appearance. You'll also find that there are high res textures for use with Risen3D that can also be used with jDoom, but again, they're not exact replicas of the originals.
Of course, you're welcome to create replacement texures that are more faithful to the originals, along with replacements for the original textures that were never completed.
