I'd like to provide my opinion based on some observations:
First, human eyes have probably evolved to work in natural daylight. This corresponds to [CIE D65][1] standard, which "is intended to represent average daylight and has a correlated colour temperature of approximately 6500 K".
Second, the other common recent trend is dark theme everything.
The common cause for these seems to be an excessive brightness. My simple rule is a screen filled with white should not cause eye discomfort. That's it. Lowering color temperature and switching to a dark theme are different means to a common goal of lowering overall display brightness. Warmer colors are perceived as softer and less bright. Dark theme is an overengineered way to make display darker.
I believe the "blue color danger" is/was an artificially inflated hype to sell browser/os extensions. Since most OS nowadays have color temp controls built in, unaffiliated research started to emerge.
Why is a dark theme "overengineered?" You can't just arbitrarily turn down the brightness of a screen and still be able to read it. There's a minimum level of contrast required. Dark themes retain that minimum level while still greatly reducing overall brightness.
