Re: [csswg-drafts] [css-color] lab and lch color spaces should use the D65 illuminant commonly used for digital media (not D50) (#9061)

You are correct that D50 is typically used for physical measurements, like reading a surface color with a spectrophotometer. Also, as you note, in ICC profile processing, where Lab is the profile connection space. 

Which is why it was chosen: for compatibility with industry usage. This was not an error.

Oklab, which improves on CIE Lab in many ways, uses D65.
