(I hate having to make these statements but I am not trolling)

I was told search for "perfect" parity across users was in vain because perception of colour varied too much, from blood sugar level to physiology and etc. What is the true benefit of going after this on software side? I mean I am not understanding the difference it causes on artistic statement or emotional impact.

I understand and support "true colour" across all hard/software but is it really that impactful?

We're not talking about perceived colour in these articles. Instead at best we're talking about absolute colour as might be sent over a display cable or as might be presented on a calibrated screen. Even if the screen isn't calibrated or the user is partially colour blind, the values that are sent over the HDMI or DisplayPort cable do still matter. Those values tend to be 8-bit 0-255 values for R, B and G, though that's starting to change. I won't get into how 255,255,255 might be a different colour depending on what mode your computer monitor is in or how your cable signals the mode to the computer monitor, but the point of this article is that the colours in a video can vary based on how and when the video was recorded, mastered, etc. This is partially historical: if watching a DVD you'll have a smaller colour range than if watching a UHD 4K HDR Blu-Ray because back then most TVs couldn't display high contrast images or what we now refer to as HDR or Dolby Vision. There are other concerns, of course, such as framerate and resolution and even the shape of a pixel can change in some video files. So ... it's a complicated topic. :)

I doubt the blood sugar level is more important to color than different display types/models and/or different rendering software.

I think the issue is more about consistency than true color/fidelity as true fidelity/color sharing between individuals is impossible at this time. Professional video equipment exists for a reason.

One of the major user stories is "I have CSS and a video on my page, and my colors should match".

Another is the desire for product photos to look relatively true-to-life, so you don't order something and it's too dark, or too red, etc.
