I think someone needs to reacquaint themselves with a few of Mark Schubin's video talks:

And if you don't have the attention span for all four of the above videos, here's a summary:

High Dynamic Range gives you more "bang for your bit" than 4K spatial resolution.

The article makes the usual arguments, diminishing returns, viewing distance, and so forth.

But we are grown-ups now, and we should have a sense of déjà vu. Precisely the same arguments were made ca. 1995-2000, which is why they might sound original to millennials.

HD became essentially mandatory, for TV screens that are commonplace today. The naysayers back then were thinking in terms of the typical CRT-sized displays of the day. Remember when a 35" was huge (and grainy, washed out, and fuzzy)? In the not too distant future, we'll probably be making another step up in size.

The comments to the article are more insightful than the article, I might suggest. Don't TVs in old movies seem small and quaint? What would make anyone think that time will stand still? A wall-sized display, in a home setting, would likely be viewed at considerably less than three screen heights distance. We probably should consider incorporating a 4K transmission mode?
