Someone please tell the Australian government now that we've essentially banned other forms of lighting. (except fluorescent)
The article uses LED as synonym for typical LED lightning.
10 years ago you had to work to find high CRI bulbs but could still find Cree bulbs pretty easily. Now you can get high CRI bulbs at the grocery store.
High CRI bulbs generally have low or no flicker because high CRI is toward the premium end of the market.
IR emission is not a "feature", it's a bug.
Out of the manufacturers you listed, only Philips Ultra Definition (95 CRI, R9 90) have low flicker and good R9. Unfortunately they are poorly made and I have to keep buying new packs each year but it's more cost effective than Yuji for lesser used areas.
Also the claim from TFA is that NIR component improves visual performance (and I've read elsewhere that NIR also has health benefits).
If you look at energy efficiency, it totally is. But the whole point in the discussion is that IR _might_ (according to the paper) have biological relevance.
Also LED lighting can have infrared, have a significantly more smoother spectrum curve and still last +20k hours without burnout. The cheaper bulb spectra that they show is a blue led + phosphor coating, but there are infrared LEDs, UV leds, and more. You can make quite the convincing sun simulation, even better than any incandescent bulb, but there is almost no demand for UV + Infrared super full spectrum lighting unfortunately. Only movie & theater lights come close.
Do you have a link to a bulb that you can purchase meeting all these criteria? The only one I'm aware of was this obscure "StarLike" that was never actually sold in bulk. LEDs can be made good in theory sure, but in practice they are all terrible in light quality compared to a standard incandescent.
No, you can't buy them as bulbs. The closest thing is those red light therapy panels that include them.

You're paying through the nose though, but it finally exists now.
Do you really think $5 AUD per month per bulb that you’re running 8 hours a day is worth it for better spectrum quality?
This isn’t some kind of controversial subject. Ensuring home appliances don’t overconsume energy is beneficial for everyone in society.
You don’t want to have brownouts, blackouts, or run out of heating gas/oil in the winter.
You bring up the idea of regulating computer equipment power efficiency as if it’s crazy talk but it’s a real thing in concept. Governments do offer guidance and sometimes regulate computer efficiency. They have efficiency standards (e.g. Energy Star) as well as relying on industry standards (e.g. “80 Plus”).
Take a look at your computer monitor or TV box and it probably has an energy star logo somewhere if you live in the US.
The US federal government and other state and local agencies will not buy computer products that aren’t energy star compliant, and encourages businesses and individual to follow similar standards. Other countries might regulate further than these (dis)incentives.

And if you bring up data centers, those are considered productive industry that has its own regulations different than home regulations. Plenty of things legal in industrial series aren’t legal in your house.
Lightbulbs on the other hand affect all of society, so they've got a much larger impact to the overall CO2 budget.
Additionally, the average person uses a laptop or mobile devices, all of which use less power than even a single typical incandescent bulb (and people usually have many lightbulbs).
Replacing incandescent bulbs with LEDs saves a lot of CO2 at basically zero cost, while getting rid of computers saves less CO2 for a much larger economic impact.
And even the effect described by this article has to be looked at in context, considering most of the light people experience in a day — and have experienced for the since homo sapiens existed — is natural sunlight, even in northern Europe during the winter (that's why EU law mandates windows with sunlight in every office, apartment, bedroom, etc.)
