Right. Just like the article, HDR is too vague to mean anything specific and a label that's slapped onto products. In gaming, it often meant they were finally simulating light and exposure separately--clipping highlights that would have previously been shown. In their opinion, reducing the fidelity. Same with depth of field blurring things that used to not have blur.

It's HDR at the world data level, but SDR at the rendering level. It's simulating the way film cannot handle real-life high dynamic range and clips it instead of compressing it like "HDR" in photography.
