Does BT.2020 mean my video is HDR?
Not by itself. BT.2020 describes colour primaries. Look for a transfer function such as PQ or HLG, or Dolby Vision metadata; missing tags leave the answer uncertain.
Can this checker verify HDR on my screen?
No. It reads source metadata, not pixels or display headroom. HDR rendering also depends on your player, display, brightness and macOS settings.
