i know the new ipad pros have hdr playback but arent 4k screens. Im getting me the new apple tv 4k and a new sony 4k tv next month but in the meantime will this upgrade add hdr to some of my movies on my new 2017 ipad pro 12.9 inch? I would guess so. Yes i know the pros dont have the 4k resolution but they should still in theory be able to handle the HDR right? Im re downloading a few movies on my pro now and going to compare it to the films on my 7plus to see if their is a color diffrence. (Yes I know about turning off true tone at night shift to get a better test) but apple wasnt totally clear on the details and im a bit confused.
