The color of the environment map is displayed brighter than r98

I tried webgl_loader_gltf sample with three.js r98 and r99. As a result of comparison, r99 seems to be slightly brighter than r98. I think that it is necessary to specify THREE.sRGBEncoding in the environment map if it is over r99.

However, applying THREE.sRGBEncoding to the environment map will make the model darker, so I think further actions are necessary. Unfortunately I do not know how to do it.

three.js r98 result:

three.js r99 result:

three.js r99 + sRGBEncoding result:

@tsuchan See https://github.com/mrdoob/three.js/wiki/Migration-Guide

renderer.outputEncoding = THREE.sRGBEncoding; // alternate: THREE.GammaEncoding

My two cents:

I would suggest that roughness, metalness, glossiness, normal, bump just be linear always. It sometimes will be slightly wrong but I doubt people will notice.

Only the color channels should allow for decoding, either sRGB, or linear. I would suggest handling sRGB/etc decoding in Javascript and assume within the shaders that all uniforms are in linear color space. The last thing we need is more complexity in the shaders, especially a decode per pixelshader instantiation that is exactly the same each time (and another DEFINE or uniform - there are too many of those already.)
