Yes that is for everything but the image editor brush colors. They are not gamma correcting the hex values you enter. I want to make a 👾 report about it specifically for the brush color.
It doesn’t need to change (they intend to have it that way) but the description on the HEX says it is gamma corrected when it is not.
try it yourself: enter 0.5 on the rgb channels for a texture brush and do the same on a material color. You’ll get different hex values for the same linear rgb.
