Know Which Service Streams Best
๐ธ What is 4K Stream Check?
It's a real-time filter that shows which 4K movies are available across services including Netflix, Prime Video, Disney+, Paramount+, HBO Max and Stan (AU) โ based on format quality and platform support.
๐ธ How are region matches handled?
Region filtering is automated. If a 4K title is available in your region and globally, it will be shown.
๐ธ Why do some filters require selecting more than one service?
To enable fair cross-platform comparisons, 4K Stream Check requires a minimum of two streaming services selected. This ensures the listings are meaningful, not just isolated results.
๐ธ What are HDR and audio format filters doing?
These detect whether a movie supports Dolby Vision, HDR10+ or Dolby Atmos based on metadata.
๐ธ How are HDR formats ranked?
Dolby Vision is ranked highest, followed by HDR10+, HDR10 and SDR. Here's why Dolby Vision often wins:
- ๐น Uses a 12-bit color pipeline (vs. 10-bit for HDR10/HDR10+), enabling smoother gradients and better tonal detail
- ๐น Supports dynamic metadata โ like HDR10+ โ but with broader adoption and stricter hardware certification
- ๐น Often mastered at higher peak brightness (up to 4000 nits or more)
- ๐น Falls back to HDR10 on unsupported devices (HDR10+ can drop to SDR instead)
๐ธ Is peak bitrate more important than average?
No โ the tool prioritizes average bitrate over peak values when comparing services. Peak bitrate can be brief or misleading, while average bitrate better reflects real-world streaming quality across an entire movie.
๐ธ Why does Apple TV (iTunes) show up if itโs rental/purchase only?
Apple TV (iTunes) is included as a high-quality reference point. Since it's a paid platform, many titles offer maximum available formats โ including full Dolby Vision, HDR10+, Dolby Atmos audio and often higher bitrates โ making it a valuable benchmark for comparing technical specs across subscription services.
๐ธ Are results based on live availability?
Yes. Data is updated regularly and the filters reflect the current known status of each 4K title in real-world streaming catalogs.
