sRGB encoding as a postprocess pass

You’re right. The difference is pretty noticeable.

I don’t think the difference should be that noticeable. But in any case, you can just write your own sRGBCorrectionPass.

Use the gammaCorrectionPass as a template:

mrdoob/three.js/blob/205e345b4f48f8b560b3b35391fd914cba1997a0/examples/jsm/shaders/GammaCorrectionShader.js

And you’ll find the LinearTosRGB function here:

mrdoob/three.js/blob/205e345b4f48f8b560b3b35391fd914cba1997a0/src/renderers/shaders/ShaderChunk/encodings_pars_fragment.glsl.js#L20-L22

You don’t need to redefine the function in the pass, since the pass has access to the function defined in the core. Simply replace LinearToGamma with LinearTosRGB in the GammaCorrectionPass.
