Your post has nothing to do with iTunes 4K upgrades!Yesterday I bought The Big Country (1958) from VUDU for $7.99. I thought it would be nice to have a Digital copy at a nice price. It was in Full screen ! Not in Widescreen 2.35:1 like the KL Bluray. I got a Refund. Why don't they have these movies in the correct aspect ratio ? Also ...Jason and the Argonauts Digital is a Old version with Dirt and specks all over it. Nothing like the Sony Bluray. Got that Refunded from itunes weeks ago. These Digital companies need to update their movies with the Best versions available.
