I have a question about using HDR visual content in visionOS, especially inside a volumetric window or an ImmersiveSpace.
For example, if I display an HDR photo or use very bright lighting on reflective materials, I can sometimes trigger a noticeably higher peak brightness on Vision Pro. However, in my testing, this higher brightness only lasts for a short time. After that, the overall scene brightness appears to be reduced automatically.
I would like to understand the intended behavior and recommended usage pattern.
Specifically:
Is HDR image content recommended for use inside volumetric windows or immersive spaces?
Are HDR photos or high-brightness reflective highlights intended mainly for short-duration local highlights rather than sustained full-scene brightness?
Does visionOS apply automatic brightness, tone mapping, thermal, or power-related management when immersive content contains very bright HDR areas?
Are developers expected to avoid large or sustained high-brightness HDR content in immersive scenes?
What is the recommended way to author HDR images, bright highlights, emissive materials, or reflective materials so they look realistic without causing the whole scene to dim?
Are there any visionOS-specific guidelines for HDR content, peak brightness, average scene brightness, or comfort when presenting HDR photos or bright 3D materials?
My goal is to use HDR content responsibly for realistic highlights, reflections, glass, metal, or photo display, while avoiding visual discomfort or unexpected global dimming behavior.
Any guidance would be appreciated.
