Support for linear color mode?

[TheHackerDev]

According to this comment in the code, linear/sRGB textures are not supported. Is this still the case? Or is it an outdated TODO comment?

I'd like to know before going through the process of installing GLTFUtility, because I need to support linear color mode for my game to work on the Oculus Quest 2 (loading a glTF file dynamically from a URL and rendering at runtime).
