This reuses the HDR tonemapping curve that was used in RenderEngine, however display-level metadata may not be aligned. But because there are no composition changes that can cause flicker, e.g., switching rapidly between using a TextureView and a SurfaceView, then that should be okay. That means that the HDR tonemapping is not as high quality as it could be, but it is much better than before. Bug: 200309590 Test: builds, boots Test: Instagram video preview Change-Id: I4dd042333f383f383d568b6f2326ee14facd08ed
