Let's look at that paragraph:
Meanwhile, Samsung — one of the biggest HDR10 proponents — seems to still be sticking exclusively with that standard even with its newly announced flagship sets, but that doesn’t mean it’ll be missing out on any HDR content.
And they’re WRONG, as they admit in the next sentence: Of course, all this only is true if manufacturers decide to provide support for the various formats.
Because the manufacturers will NOT provide support for multiple formats. People insisted HDDVD and BluRay could peacefully coexist too, until it became obvious they couldn’t. Learn from history, people who bet wrong in format wars ALWAYS get stuck with dead end technology that isn’t supported and cannot make use of the high end features that’s why they bought it in the first place.
