> To see HDR content at its full dynamic range, you'll need an HDR-capable device or display.

Not exactly - you need an HDR Mastering display to see HDR content at full dynamic range. There are essentially no high volume consumer-level devices, with the exception of maybe Apple's XDR lineup (MBP, iPad, iPhone, Pro Display) with the capability of displaying non-windowed HDR content at full brightness.

Everything else relies on tone mapping, even the latest 2022 OLED & QDOLED TVs.

Even HDR mastering monitors can only reach 2000 to 4000 nits [1], whereas PQ gamma goes up to 10000 nits. This is why most hdr streams contain metadata containing mastering display peak luminance.

Good info, thanks! Can you elaborate on why you qualified this with "non-windowed"?
