I could specify a RGB color in Photoshop(...) as well as using the same RGB values in a color picker
Hi chocbot, I am quickly chiming on this quote: R'G'B' itself is a color
model and not a color space (that is composed of three components, detailed in the link below).
I believe that what you are referring to, is an "sRGB color picker value", likely display-referred (with the
electro-optical transfer function applied, mistakenly known as "̶G̶a̶m̶m̶a̶ correction").
If you are interested, I could recommend this informational content:

In case you are unaware, the workflow could be much simpler
without ACES while still having a similar "look". ACES being often overkill for the majority of individuals, uneducated about the digital imagery fundamentals. More information can be find in the link above.
