So far I have 4 films in my iTunes purchases that have been upgraded: iIdependence Day 1 & The Martian (both HDR10) and The Lego Batman Movie & Fantastic Beasts (both Dolby Vision).
The Martian shows quite a difference from the non-HDR version. The daytime Martian surface shots show a deep vivid orange contrasted with deep, inky shadows which still show plenty of detail. They’re no longer ‘crushed’, ie where shadows are just huge swathes of black area with no detail in. The vivid colour contrasts give a great impression of an alien world.
The Lego Batman movie takes what was already a vividly coloured, high contrast picture and ramps it up to 11. What you get is eye searing contrasts as the reds, green and blues burst out of the screen. All of this is quite intentional and suits the film’s cartoon, everything cranked to 11 sensibility just fine.
Fantastic Beasts is much, much more subtle. Many scenes are muted and have an almost sepia photograph look. HDR is still there but used to a subtler, period evocative look.
Independence Day? I’m not convinced I’m yet able to stream the HDR version. What I can stream today on my iPP doesn’t strike me as any different looking to the film I watched with my 10yo from iTunes a couple of weeks ago on our regular telly. Not bad looking by any means, in fact it looks great compared to the laserdisc I bought way back when, but if this is the HDR version I was getting, its barely noticeable. WIll check back next week after the iOS 11 and ATV 4K general releases.
We’re still in the pre-IOS11/ATV 4K era today and the iTunes Store is still in the process of being updated. We should have a far better idea of what is available content wise and Apple should have confirmed via the tech spec pages exactly what our iPPs support,
