    According to Apple the new iPad Pros are still 600nits and full P3 color but all references to HDR seem to have been removed (both for the new and old models).

    It seems like they still perform the same on a hardware level but it would suck if iOS no longer decode/downloads the HDR versions of movies for some reason.

    Don’t you need a OLED screen in order to get HDR?

    That's what I thought! HDR10 or Dolby Vision! My wallet is very happy that the iPad Pro doesn't have OLED.... :D
    I think that would have pushed me over the edge to grab one!

    No.

    But AFAIK you need a screen that is capable of at least 1000 nits of brightness and support of 10 bit colour.

    No, you don’t need OLED to have HDR.

    Well no offense.............. although Apple states that HDR works on the ipad pro 10.5, the movies that do play in HDR on netflix don't look like true HDR. The netflix HDR movies on my galaxy tab s4 do look like true HDR....

    @jamesrick80, I stand corrected...

    Gah!!!! poor wallet!! I will have to play around with one of these in the store, brightness shows 600 nits, which seems sufficient for peak brightness..

    would be awesome with the following stats:
    More than 1,000 nits peak brightness and less than 0.05nits black level.

    So, if you can only have HDR in combination with an OLED screen, how can my Samsung KS8000 TV have a LED (not OLED) display and offer 10bit and HDR. Same for most high end Samsung TVs and other brands. ;)

    For HDR one needs a wide color spectrum and a certain nit level. E.g. 600nits in combination with 10bit is HDR600. :)

    No. You have HDR400, HDR600 and HDR1000. E.g. for TVs you need a minimum of 1000 nits.

    When it comes to laptops, tablets and phones they also offer 400 nits (HDR400) and 600 nits (HDR600).

    10bit is a must. :)

    Oh okay so that means the new Pros should support HDR.

    In theory, yes, but it seems Apple did not certify their display, hence some apps like YouTube might not enable HDR content for the iPad Pro. :(

    HDR is mainly about 3 things

    High contrast ratio:

    Contrast ratio is the difference between brightest and darkest level.

    OLEDs naturally have insanely high contrast ratio as individual pixels can be turned on and off and various levels in between (XS has 1,000,000:1 contrast ratio).

    LCDs need local dimming that divides the display into several regions and apply different brightness level for each region. Without local dimming, LCD applies the same brightness across the entire screen, making darkest part washed out (grayish) or the brightest part less bright (full brightness across the entire region would consume more energy and light source, neither of which are yet possible for consumer grade displays). Older iPad Pros and iPhone XR (1,400:1 contrast ratio) do not have local dimming. Maybe new iPad Pro has local dimming but I doubt it.

    Wide color gamut:

    Ideally with 10-bit (HDR10) or 12-bit (Dolby Vision) display panel. All Apple devices, except 27" iMac and iMac Pro have 8-bit display panels (27" iMacs and iMac Pros have 10-bit). iOS's automatic color management feature maps P3 color gamut to 8-bit display, well enough for very good HDR-level experience.

    High luminance:

    Ideally 4,000 nits (HDR10) or 10,000 nits (Dolby Vision) peak brightness, but no consumer display approaches anywhere near that.

    SDR is typically 500 nits peak brightness and HDR10 and Dolby Vision recommends (but not require) 1,000 nits peak brightness. Great HDR TVs can approach 1,000 peak brightness over small region.

    New iPad Pro has 600 nits, iPhone XR and XS have 625 nits. iOS uses tone mapping to adjust HDR10 and Dolby Vision brightness for the device's limitations.


    Since older iPad Pros can playback HDR contents, I am guessing new iPad Pros can also. High contrast ratio is probably out as Apple hasn't offered local dimming on any LCD so far. But I am guessing new iPad Pro will at least benefit from wider color gamut.

    I always thought the latest iPad Pros had a real 10bit display...especially now they want to aim for a professional creative audience, 8bit would be an absolute NO GO..... I don't even edit 8bit videos anylonger. All 10bit! (4k HEVC 10bit 4:2:0 or 4:2:2). Let alone for 3d editing and high profile image creation. 10bit or higher is essential.

    There's a lot of confusion about what does or doesn't qualify as HDR. My point wasn't so much defining whether the specs are sufficient for "real" HDR as pointing out that the specs are the same and yet Apple doesn't mention it so it seems like these displays might not display HDR content or be certified.
