Prime Video makes 4K pay-to-play with new Ultra tier
Amazon Prime Video is restructuring its plans: basic Prime Video will be capped at 1080p, while 4K/UHD requires the new Ultra tier at $4.99 more per month. Ultra adds more offline downloads (up to 100), Dolby Atmos audio and Dolby Vision, and more concurrent streams (up to five). Basic members will gain Dolby Vision support and increase from three to four concurrent streams; true 4K remains bandwidth- or device-dependent for many users.
