three.js is using SRGB8_APLHA8 for sRGB encoded textures. That works fine for textures loaded via the <img> or <canvas> tag.
three.js provides a video texture class based on the <video> tag like demonstrated in the following example.
https://threejs.org/examples/webgl_video_panorama_equirectangular
As you can see, the colors are washed out though. That's because when configuring the video texture as SRGB8_APLHA8, the color space conversion to linear-srgb does not work anymore.
The demo does work as expected in Edge, Chrome and Firefox.
