Hi @BenKlesc - thanks for the post. You are correct about flicker, since most OLED panels today flicker at around 240Hz. I also appreciate the comment about brightness, since this is perhaps the biggest factor that determines how much light people see.
However, the information you're posting about blue light is not correct. A few years ago, several companies would pick a range of wavelengths and see how much power was in a particular range, but there is no agreed-upon range like this used in the scientific literature, or in an international standard. Numbers like "6.5% blue light" do not have a "standard" meaning - this is mainly marketing that does not have a physiological basis.
That leaves three metrics to consider: s-cone activation, melanopsin activation, and a purported "blue light hazard":
Any screen (and especially one with a wide color gamut) can produce intense blue, and this is just a fact about univariance in the cones. So if you are talking about the visual sensation of "blue" there is no difference in which wavelength is used: the s-cones will see this light the same way.
On a melanopic level, OLEDs today make about 23% more blue-green light than do LED backlights. So there is no advantage to OLED in this regard.
Some people are using the IEC-62471 "blue light hazard" factor, but these hazards are intended for use with extremely bright lights (like lasers) above about 10,000 cd/m2 (more than any screen today), so I think the methodology is improperly used. Still, even on this level, OLED is only about 10-15% lower "hazard factor" - a very small number, since these effects happen over orders of magnitude. If you think there is a blue light hazard due to screens, you'd want to change it by 90% or more (f.lux does). In contrast, most of the filters using this metric today make very minor changes (5-15%). But it's important to say that currently, we think even the use of this metric is inappropriate, given what it was designed to measure, which is extremely high levels of light.
We have some measurements of various devices online here:
