Well erm no, it's never been like that if you think about it
. You can easily demonstrate it by setting all the settings the same in all four modes, and then switching to "Dynamic" and the misnamed "Natural" mode, the colors are massively different. The color settings you enter in Expert/Colour Space/Custom are offsets
from Samsung's multiple preset values. So to get "correct" colours in all four modes you'd have one set of offset values for Movie, a different set of offset values of Standard, etc, because the starting positions
for Movie and Standard are different (and hard-coded and impossible to change).
This is why sometimes, on some TVs, a calibration may be quite odd - such as start with a whacky mode, and then enter a particular set of offsets - because that ended up with the closest set of colours to "correct." (for example, my previous Samsung TV's calibration had "deep colour" and "xv color" turned on, and then some other values "wound back" to bring everything into line for a final result which was more accurate than was possible by adjusting the values for the normal Movie mode)
It's also why it's very likely to be utterly impossible to get accurate colours in Dynamic and the misnamed "Natural" mode even with professional equipment and entering all values in Expert/Colour Space/Custom in those two modes - because the starting positions in those modes are so whacky.
We're very luck in that, unusually, our TVs have an almost-perfect out-of-the-box accuracy for colours in "Movie" mode, so this is why using Movie and Colour Space="Auto" is pretty much bang on.
The other thing to remind people of is that only Movie mode offers full 10-point white balance correction
. So, if you've been professionally calibrated, it's probably for the Movie mode.
However since we're not (well, most of us!), and we've probably all left the 10-point white balance in Movie well alone, and the 2-point white balance in Standard well alone, there's less of a difference in the modes.
We're left with the starting point
of what Movie/Expert/Colour Space=Auto is, vs what Standard/Expert/Colour Space=Auto is. And of course, both
would need professional kit to measure accurately.
