Here is what a genuine S02E09 Lossless file should contain:

Title: Family Dynamics and a 4K Upscale Original Air Date: December 6, 2018

If you find a 4-6 GB x265 encode with FLAC audio (instead of the massive 12 GB REMUX), that is a "transparent" compromise. You get 95% of the visual quality with 90% less storage.

| Feature | Streaming (Max/Netflix) | Lossless/REMUX | | :--- | :--- | :--- | | | ~8-15 Mbps (HEVC) | ~25-35 Mbps (AVC) | | Audio | Dolby Digital 5.1 (640 kbps) | Dolby TrueHD 5.1 or DTS-HD MA 5.1 | | Subtitles | Compressed/OCR'd | PGS (Blu-ray bitmap originals) | | File Size | ~1.5 GB | ~8-12 GB |

Happy hunting, and enjoy the letter scene with the lights off and the volume up.
