static void recursivelyMapIOSurfaceBackingStore(CALayer *layer)
{
    if (layer.contents && CFGetTypeID((__bridge CFTypeRef)layer.contents) == CAMachPortGetTypeID()) {
        MachSendRight port = MachSendRight::create(CAMachPortGetPort((__bridge CAMachPortRef)layer.contents));
        auto surface = WebCore::IOSurface::createFromSendRight(WTFMove(port), WebCore::DestinationColorSpace::SRGB());
        layer.contents = surface ? surface->asLayerContents() : nil;
    }


DestinationColorSpace::SRGB!

Also:
                case RemoteLayerBackingStore::LayerContentsType::IOSurface: {
                    auto surface = WebCore::IOSurface::createFromSendRight(WTFMove(machSendRight), DestinationColorSpace::SRGB());
                    contents = surface ? surface->asLayerContents() : nil;
                    break;
