WebXR Stereo Texture gamut issue

I am testing WebXR, via BabylonJS, on Vision Pro. Stereo 360 photos are extremely common, and a vital part of my application. However, Safari shows the texture as quite a bit lighter and more contrasty than is correct, almost like the wrong image gamut. This only seems to happen with the stereo domes, the displayed image has correct contrast when non running via WebXR. I'm hoping someone has seen similar and has a workaround, or a tracking bag.

Cheers!
