iTunes 1080p Isn’t Quite Blu-Ray

You remember a week ago when Apple introduced full-HD content on iTunes? It was 1920 by 1080 pixels resolution, which is supposed to be the same as that of Blu-Ray. Sadly, even though it does come close to the beautiful Blu-Ray quality that most high-definition content lovers are used to, it’s not quite a digital rival as it should be. This isn’t at all surprising since most iTunes films are an average of 4 GB, as opposed to a 40 GB Blu-Ray film…

Ars Technica reports today that even though Apple’s 1080p iTunes content does look great, there aren’t as many details in the picture as Blu-Ray disks have, meaning that iTunes isn’t quite on par with full-HD just yet. In addition, dark gradients seem to look a bit more distorted on iTunes’ format when one looks closely. For instance, in the capture above you can see that there are a few extra artifacts in the image from iTunes than in the Blu-Ray copy. It’s not much, but it can be noticeable to some.
