Apple TV iTunes: 4K HDR Titles (Bitrates, Peak/Avg Brightness, Atmos) Thread

[thebox]

In addition to the excellent Bitrates spreadsheet created by @lgans316, this thread is dedicated to cataloguing and discussing 4K HDR titles available on Apple TV iTunes (for purchase/rental), focusing on bitrates, peak/average brightness (HDR metadata) and Dolby Atmos performance.

I'm committed to updating the thread weekly (starting with daily updates) with newly added 4K titles to my library and data points. If you have tools for testing or insights to share, feel free to contribute your own findings!

The goal is to provide broad tech info while allowing members to make digital purchasing/renting decisions based on their individual tastes, assuming these tech details can play a role in their choices.

P.S: HDR metadata (retrieved using an HDFury Integral 2 device), when present, helps displays perform proper tone mapping by providing info about the content's brightness levels and guiding their tone mapping curves. Some HDR content lacks metadata or has incomplete metadata. In such cases, displays rely on their built-in tone mapping algorithms, which may result in inconsistencies in HDR reproduction.

P.S2: General audio bitrates on Apple TV iTunes are as follows:
Dolby Atmos: 770 kbps
Dolby Digital 5.1: 386 kbps

P.S3: I use an automated setup to analyse Dolby Atmos (or EAC3-JOC) on streaming services. My process includes: calibrated microphones (MiniDSP UMIK-1), an HTPC with REW and Python scripts and playback of key scenes. Audio is captured from the AVR to evaluate height channel activity, dynamic range, dialogue and LFE (still fine-tuning). Results are processed through my trained AI model, comparing data to Dolby Atmos reference demos to generate a score (30–50) and a brief report.
I also compare the results with my subjective impressions, making minor adjustments if needed. For height channels, I focus on usage frequency during key scenes, simpler than object-level decoding like a Trinnov, which is far more costly!

P.S4: For Dolby Vision/Atmos grading, I rely on IMDb's Tech Details (verified via API), to check if a movie was graded in Dolby Vision during post-production, a 4K remaster or converted from HDR10 at the streaming level. IMDb is a reliable reference for blockbusters but less so for niche titles, so I treat it as a guideline rather than definitive proof!

P.S5: Bitrate details:

Peak Bitrate (Static): ~XX Mbps
Average Bitrate (Static): ~XX Mbps
Real-Time Average Bitrate: ~XX Mbps

Where:​

. Static values are set by the streaming service
. Real-Time values are measured during playback.
