finding a way to implement booklike render (like vermintide 2 trailer)

[GameMadeByGamers]

Im currently researching how i would accomplish a similar render to the trailer of vermintide 2 Shadows Over Bogenhafen :

Warhammer: Vermintide 2 Shadows Over Bogenhafen DLC Trailer

Will it be more performant to just postprocess effect via Graphic.blit() or would it be more practical in form of shaders?

The effect are easy not that hard to reproduce the distorting rim/fresnel effect but i was wondering if the ink like effect was just saturation and dithering base on camera distance in lighting, those are easier to do in postprocess vs shader (i only know how to make the shader react to the main light, though im working on some hlsl custom node).

If someone has some source/reference or documentation on something similar i would be interested.

Thanks in advance.

Looks like basic cell shading technique to me, the white glow is basically the toon outline, push back to not have interior line and with a fresnel alpha feather to blend with the background.
