iPhone 13 Dolby-vision in films and TV

[Narcisus]

I’ve just been watching Foundation and noticed the phone brightness stayed where it was before at about half brightness.

Have I missed a setting or do you have to manually increase the brightness to full with HDR content ?

[mmm-five]

I don't have an iPhone 13, but surely it's using Dolby Vision to convey the film makers idea of what colours/contract the film should look like, rather than the overly bright, over saturated fake HDR that you see in promos.

I know film maker mode is less bright on my OLED than 'HDR' mode - but the contrast between dark shadows and bright highlights still hurts my eyes sometimes.

Mmm brightness appears to stay where you put it. Turn it right down it stays down.

I have a similar film setting on my LG oled and it asks me if I want to use it but not on Dolbyvision content.

I though the idea behind hdr was to have that super brightness available ?

No, that's not really quite what it means. High dynamic range means that the movie is processed to allow detail in the darkest parts of the screen, whilst at the same time allowing lighter screen areas to still also be detailed and not 'blow out' (this used to be done using two or more lenses with different apertures, then lacing them together programatically to show the best parts of each, but how it's done now I don't know, maybe just software). Adjusting the brightness on your phone will just change the brightness on your phone screen for everything. Dolbyvision is supposed to be richer, brighter and more accurate colours combined with the HDR revealing increased detail.

OK Not sure how that works on the iPhone then just been having a google and it appears when watching HDR content you just have to manually ensure your screen brightness is at maximum.

Just seems a bit clunky…
