Apple Vision Pro washed out / lighter colors about aframe HOT 8 OPEN

Seems might be due to Vision Pro displays being p3. Might need some spec work. Found relevant convo.

Thanks. I've been told Apple team is aware of it and working on it. I think timeline depends whether it requires modifying the WebXR spec or not.

This is annoying. In theory all we'd have to do is set outputEncoding = THREE.LinearSRGBColorSpace on the WebXR render target. However, this isn't the case for all pre-existing supported devices, meaning:

• A check is needed to determine if the device is an AVP or not, and depending on it set the output encoding
• Shaders like the ones in aframe-environment-component won't output the correct colours on AVP (= requires changes)
• Projects that require colorManagement: false will have incorrect colours on AVP
• Projects stuck/still on older A-Frame versions will have incorrect colours on AVP

Not to mention, that if Apple changes it to be in line with the other implementations (or vice versa), any workarounds already in place will instead cause incorrect colours. Not sure what the best approach going forward is, but since WebXR is still behind a flag on AVP, I think an opt-in property or something would be safest, until it's clear if this behaviour is intended or not.

Short term hack might be necessary:

@dmarcos any updates on a fix for this? I had tried manually adding a gamma correction in a shader and it helped a little but wasn't great :s It's making our splats look sad in https://github.com/mkkellogg/GaussianSplats3D

@mkkellogg FYI

@dlazares This has to be fixed at the Safari / WebXR spec level not A-Frame

thanks @dmarcos, tracking is here https://bugs.webkit.org/show_bug.cgi?id=270465 and also a short-term hack described in it as well.
