Color vision is the function of either trichromatic sensory vision or tetrachromatic sensory vision (20% of the population)

That means you either have 3 color sensor, or 4 color sensor.

In the case of color blindness, it's a blanketing term that covers many abnormalities, in MOST cases, what you have is 2 of sensors that have a response curve very close to one another, for example Red-Green. They call it red green, but it impacts all color perception.

Normally , there is a bigger response difference between the sensor, that helps with differentiation, but it is "posited" that red-green colorblindness improves detection of camoflage predators in nature, which is why it is sometimes (not always) for the SPOTTER personel assigned to snipers to be a colorblind person.
My point was that I am actually colorblind. Most of the explanations come from people who understand the science behind it, but have never actually experienced it. The difference between a 16-bit color image and a 24-bit color image to me is extremely minor.

In most cases, these should be OK, but again, beyond 5 years, even with the glass sensors, depending on storage , etc, not reliable.
Good to know, and thanks for that info. I definitely don't feel as clingy to a calibrator I paid $50 for compared to full retail, and will be more likely to periodically get a new(er) one if I can keep getting them at that price point.

I calibrate yearly, and didn't see seen much (if any) change from my 2019 calibration to my 2020 one..

calibrations drift within 300 hours of use. the panel will have no semblance of accuracy in the span of a year.

They don't tell you this, and it's why people keep buying new tvs, because it drifts so much, it turns to trash basically.

bitdepth does not have any impact on your colorblindness, nor does your colorblindness impact bit depth.

The gamut is the gamut regardless of bitdepth. You can measure a boat in inches or millimeters, one number has smaller gradation (larger bitdepth), however it's the same length.

There are more shades in between, for smoother gradation in high bitdepth image, but this is not an issue in modern systems, because all images go through Dithering.

Most people will not be able to tell the difference between ANY HIGHER bitdepth vs 6-bit, Regardless if they're color blind.

Bit depth does not impact COLOR perception, it impacts gradation. This impact is minimal and imperceptible to ANYONE in modern software environments due to DITHERING.

Ok, Dr. Dunning Kruger. Now you just need to stop. You are flat out wrong. The issue with colorblindness IS with gradation. It's with the difference between shades.

Put up the color picker palette, and a person with color vision deficit will not see the same number of colors in the palette as a person with normal vision. I can confirm this from experience.

If you don't know what you're talking about, then please just don't talk. Don't go back and forth between wikipedia and these forums to find things to post.

You seem adamant about being a Victim of something.

But you greatly misunderstand BIT DEPTH. and the impact of response curve.

Please re-read my response, and think about what it is you're trying to say first.

It is impossible for you to see the difference in bitdepth , just as it is impossible for a person that's NOT colorblind to see the difference in bitdepth, in the MAJORITY of the situations regarding digital consumption.

Bit depth DOES NOT impact the Gamut.. a 10 bit monitor does not have less colors than an 8 bit monitor. It has fewer digitally addressable colors. HOWEVER, in software viewing systems, that is made unimportant because those gradations are Dithered into.

Your colorblindness responds to the Gamut differently, it does not respond to the BIT DEPTH different.
