If I play the movie using the standard player, it doesn't seem to do the tone mapping at all and I see the expected messed up coloring (green/purple hues). If I attempt to enable the native player which I would have expected to force a transcode/tone map then I get the same screen as @caffinatedutkarsh which shows the 🚫 symbol and playback never begins.
