SDR is Standard Dynamic Range. This is how most media is viewed and has been viewed for decades, typically in the Rec709 color space. 99% of consumer devices display in SDR.

HDR is a newer technology that expands the dynamic range passed Rec709 color space. It requires an HDR capable screen to display HDR content and most content is not distributed in this format, although this has been changing in the last few years.

I personally find HDR kind of a gimmick, but my point is that HDR != HD. SDR/HDR describe contrast ratios and how many colors are rendered. SD/HD describe resolution.

The chart does show them downgrading the plans from 4K/UHD to HD though.

The wiki entry has a chart which shows all plans have access to HD content. Is the chart wrong or did the contributor confuse SD with SDR?

Either way fuck HBO.
