Dr. No, From Russia with love

I bought the movies in 4k format on iTunes. When playing Dr. No a few months ago the info during the film indicated 4k format. This day the info when playing the film indicated HD, thought I believed I was still watching the 4k version. The basis start info over the movie tells that this is the 4k version. It's the same for From Russia with love.

TVOS = 15.

A small bug?
