Vision Pro中Insta360 X3 72MP全景图画质优化及参数调整问题

我使用Insta360 X3拍摄了72MP的全景图，希望在Vision Pro中实现沉浸式全景显示，已通过教程实现功能，但存在画质问题——该图在2D窗口中画质良好，在Vision Pro的3D场景中却表现不佳。

以下是我使用的代码：

struct ImmersiveView: View {
    @Environment(AppModel.self) var appModel

    var body: some View {
        RealityView { content in
            content.add(createImmersivePicture(imageName: appModel.activeSpace))
        }
    }

    /// Ref: https://www.createwithswift.com/
    func createImmersivePicture(imageName: String) -> Entity {
        let sphereRadius: Float = 1000
        let modelEntity = Entity()
        let texture = try? TextureResource.load(named: imageName, options: .init(semantic: .raw, compression: .none))
        var material = UnlitMaterial()
        material.color = .init(texture: .init(texture!))
        modelEntity.components.set(
            ModelComponent(
                mesh: .generateSphere(
                    radius: sphereRadius
                ),
                materials: [material]
            )
        )
        modelEntity.scale = .init(x: -1, y: 1, z: 1)
        modelEntity.transform.translation += SIMD3<Float>(0.0, 10.0, 0.0)
        return modelEntity
    }
}

为优化画质，我尝试调整球体半径（如设为2000、500）和缩放比例（如设为(x: -0.5, y: 0.5, z: 0.5)），但均无效果，同时出现以下警告：

IOSurface creation failed: e00002c2 parentID: 00000000 properties: {
    IOSurfaceAddress = 4651830624;
    IOSurfaceAllocSize = 35478941;
    IOSurfaceCacheMode = 0;
    IOSurfaceMapCacheAttribute = 1;
    IOSurfaceName = CMPhoto;
    IOSurfacePixelFormat = 1246774599;
}

请问我该如何调整球体半径或直接优化全景图在Vision Pro中的显示画质？

注：视线中心外画质较差是Vision Pro的自动优化机制，但即便视线中心的画质也未达预期。相关完整资源可查看我的仓库内容。
