Are iTunes Extras in 4K?

So... I’m wondering if you have a 4K Dolby Vision film and the iTunes Extras has an alternative cut of that film, is that typically in 4K DV too? It has been released on physical media in 4K.

I’m specifically thinking of Batman v Superman from the U.K. store, but I would be curious if others were the same.

Not in my experience.

Some are some are not, BvS is only 4K for the theatrical in the UK.
Doctor Sleep & Deadpool 2 to name a couple that have the extended cuts as extras are 4K.
In the US BvS Ultimate Edition is available in 4K but it’s a separate purchase.
I have Gladiator in my US account and the directors cut has just recently received a 4K upgrade in the Extras.

Most of the time they are not in 4k; just crappy 720p or 1080p. I don't know how we all survived before 4k.
