    The 10.5 could do HDR though right? Surely this one can too?

    So Apple is lying to me in the TV app when it designates applicable movies as “Watch HDR - Watch in high dynamic range on this iPad“ (emphasis mine).

    ^^ Which is the exact same behavior as on my 10.5” Pro, but of course not on my Air 2, 5th gen iPad, etc.

    No the Quality and range of range will be extended when watching hdr vs standard, it’s just not extended as much as possible and in ultra expensive televisions.

    Correct.

    Here's a good explanation:

    "Now, you can still download or stream HDR10 and Dolby Vision formats and it'll do a bang-up job displaying them, regardless of where or how you're watching, but the only way to get what everyone agrees is full-on, proper HDR is to use the new USB-C port — more on that in a cool minute — to output HDR10 or Dolby Vision to a full-on, proper HDR panel."

    Well of course. But you can say that about virtually every UHD TV w/HDR on the market. Most OLEDs don’t have the same dynamic range as high-end LCDs, but they’re still considered HDR/DV.

    And considering the quality of the grayscale tracking and color gamut of the iPad Pros, most viewers are experiencing a more accurate picture vs. when they watch on their UHD TVs at home, that are typicallly set on Vivid.

    The TV's actually aren't that expensive. And there are cheaper tablets that do proper Dolby Vision. It's just that Apple holds back features - on all their devices - for dramatic effect. Saying this as someone who bought the 1TB 12.9 today.

    “Correct” that Apple is lying? I don’t think so. There is really no such thing “full-on, proper HDR” that can be applied to an entire display category (iPad vs. UHD TV). Content is mastered for different levels of peak brightness, and tone mapping of displays can be variable on how they deal with that.

    The screen can only display about 600nits. HDR can’t be rendered at 600nits. Hdr10 I believe is 1000 nits.

    So if a display isn’t capable of displaying the contrast required.... Well then. It can’t do it.

    Eh a $500 4K TV with HDR usually has crippled HDR, you need a tv that starts at least $900 for 43” to actually start getting some decent HDR specs.

    I raised the Original question on this issue now that I have my 11” Pro in hand I have new information.
    For example. On my Samsung S8+ and IPhone X’s MAX. When you select an Appropriate YouTube Video
    That is 1080p60 HDR those two OLED phones will give you an HDR logo on YouTube Next to the 1080p60.

    Those are two OLED phones. Playing The same video, The new iPad Pro does NOT period. End of story.

    And what happens when you go into the iPad’s TV app and are given the option to watch certain movies in HDR “on this iPad” (Apple’s language here).

    The iPad Pro only fully meets the DisplayHDR 400 specifications. The 600 and 1000 levels require local dimming with current LCD technology.

    The 400 level is a joke. It pretty much just means that the screen is a good SDR screen. Even the normal iPad is HDR 400 from what I can see.

    The iPad Pro does have the color gamut and bit-depth to meet any of the HDR standards I am aware of, but it is not even close to high enough contrast. It would need about 4 times as much contrast to qualify for HDR600.

    I think it’s fake.
    Either you have broad Standard support for HDR that’s what it is a free international standard and needs to be supported fully not here or there.

    I should have really kept my 9.7” Pro for 1 more year. Because next year will be the OLED Display year.

    Not the most scientific of tests but playing red dead redemption 2 via R-Play looked awful with HDR enabled in game (looked good previously on TV) turning off HDR in game made it look a lot better
