360 Image quality too low even with 72MP How to improve or decrease sphere size

Using a 360 image that I have taken with 72MP with a Insta360 X3 I would like to add those images into my VisionPro and see them surrounding me completely as we expect of a 360 image. I was able to do by performing the described on some tutorial. The problem is the quality. On my 2D window the image looks with great quality.

I will still write down the code:

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

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

    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
    }
}

Since the quality is a problem. I thought about reducing the radius of the sphere or decreasing the scale. On both cases, nothing changes. I have tried: modelEntity.scale = .init(x: -0.5, y: 0.5, z: 0.5) And also let sphereRadius: Float = 2000, let sphereRadius: Float = 500, but nothing is changed. I also get the warning:

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

Is there anything I can do to reduce the radius or just to improve the quality itself?
