I noticed that some monitor profiling software (like X-Rite i1 Display Pro, for one example) install their startup gamma loaders under Windows 7.
Back in the XP days we used those utilities to load the LUT information into the display adapter's LUT table (since Windows didn't do it for us). However, I seem to remember coming across a bit of information about the reworked Windows 7 color management engine, which claimed that Windows 7 automatically loads the LUT information from the current monitor profile into the display adapter, thus making the gamma loader utilities redundant.
So, is this the case? Is gamma loader supposed to have any effect under Windows 7/8, or is it simply installed because the software vendor could not be bothered to recognize the OS version?
