Question: Apple 4K TV not auto change to HDR


After the 11.2 update apple tv shifts between HDR and SDR but on Amazon Prime app it doesn't. So I have the Apple TV always set to Dolby Vision but amazon shows are in HDR. When I play an episode the TV doesn't change to HDR setting, even though it correctly drops Dolby Vision as it should.

Any clue what the problem it it?

Apple TV 4K, tvOS 11.2

Actually it doesn't automatically change to match dynamic content in netflix app either.

Also, the amazon app is buggy and episodes don't play sometimes unless I restart.

What is going on? I thought the update allowed for apple tv to match content.
