They have to actually start DI'ing movies in 4k first for there to be real 4k content. Netflix has been great about their original programming as has Amazon.

That is the plan.



It is indeed.

Also worth mentioning that the pattern sample uses the 2020 matrix. We may offer both 709 and 2020 for testing as well.
