Profile 7 (used on UHD Blu-rays) contains enhancement layers (EL) – typically full EL for FEL or minimum EL for MEL. Profile 8 is designed for streaming/playback on devices like Apple TV, Shield, or LG TVs. Converting removes the EL, keeping only the RPU (Reference Processing Unit) and base layer, then repackaging into a single-track Profile 8.1 (or 8.4 for HLG).
