I realize I'm responding to an old post - but no, H265/HEVC has nothing to do with the resolution. HEVC was necessary for compressing UHD video because the file size is so large compared to 1080. I don't know what formats the studios use for compression when they film things digitally. I would imagine it still uses HEVC but it's not anywhere near as compressed as what is released on home video formats. 4K UHD discs pretty much all use H265/HEVC. I don't think I've ever seen a 4K UHD discs encoded with H264/MPEG-4 AVC.
