For 99% of films this update is going to be rather transparent. There won’t be any content changes (such as Macklunkey), but will generally be a better transfer. In particular, this relates to 4K vs. HD. I believe that their system is downscaling on the fly based on your device and your connection speed so they only need to have one version of the program on their sever to meet everyone’s needs. I can’t wait for them to update TFA on the streaming servers because it will finally be the one with no burned in subtitles. It was the only film released that way. Idiots.
