As corporations and governments continue to to grow closer to being the same thing we should expect more and more comfort on their end with flat out lying to the same level that politicians have done for decades.
They did this to whatever hbo plan I was on a while back. It was 4k with atmos, and they switched it to 1080 with standard audio while expecting me to continue paying the same price. Canceled as soon as I received that email.
Not only that, but you're often not getting the quality you're paying for due to the limitations of streaming. So, I'm not going to pay $20+ a month for what equates to 720i with garbage audio. Absolutely not.
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.
I subscribed to each streaming service for a month.
Im just really slow at accessing the vontent. Years later i'm still working my way through all the stuff.
