i sent KCinWhitby an email, but i'll reiterate here for all to read
7100K is more BLUE than 6500K (not brighter)
same as 6000K is more RED, not darker
the difference in the PC modes is not only the colour temp, but the gamma curve and contrast/brightness, which is pretty close to 2.2 and a fairly smooth curve for MOVIE and i have to assume not 2.2 and not a nice curve for the other modes (i have calibrated 2 sets in the past week for MOVIE for all PC modes and the picture was excellent for both 30fps & 24fps i.e. no crushed black/whites)
if anyone has measured the gamma curve for the other modes i would be curious to see the results
if contrast/brightness are set the same for each mode and there seems to a difference in perceived brightness, then it is probably the gamma curve
so the point i am trying to make, is don't think that grayscale has anything to do with brightness, it is the underlying colour palette and has to do with colour accuracy
in the above example, if the colour temp was 7100K, every colour reproduced has a slight BLUE tinge that cannot be removed with the COLOR/TINT controls
SPORT mode is made BLUE, because it makes ice look really bright, but artificially so
once you get used to accurate colours (which may require some time), i doubt you would want to change to any other mode and not have accurate colours
mark
PS i sent the values for 30fps into the 24fps table and altho they were close, they still required a little tweaking to get D65, so the grayscales are not identical with the same values

It seems most people are simply calibrating MOVIE (or using offsets) with Pure Cinema: OFF and again with Pure Cinema: Advanced.
I've heard that with the new version of ControlCal, we can calibrate two different A/V modes.
For instance you can have A/V Mode: MOVIE calibrated with Pure Cinema: Advanced and the color temperature at 6500k. This could be used this for critical viewing and Blu-Ray. I suspect it brings the color temperature higher in the other modes and possible renders them useless. (especially SPORT)
You can also Calibrated one other mode. So say you calibrate A/V MODE: STANDARD with Pure Cinema: OFF and brought the temperature to 7100k. This would be used for daytime viewing, 480i, 1080i, 720p. (This would make MOVIE unwatchable in 60hz as it would bring down the temp too much)
One of my hopes was that I could have a setting that could be a kind of set it and forget it. I was hoping that I could get one of the A/V modes calibrated with Pure Cinema: STANDARD so that we could still get 72hz when watching blu-ray. The problem with this seems to be that if we have already calibrated MOVIE with Pure Cinema: Advanced (72hz) and you then calibrate A/V Mode: STANDARD with Pure Cinema: Standard (60hz), when we try to get 72hz, it would bump the color temperature since 72hz is already calibrated in PC: Advanced. I hope this makes sense and of course this asumes that Pure Cinema: STANDARD is the one that can do 72hz from 1080p.
So my question is has anyone else calibrated two different modes, so that they could get a brighter temp for regular viewing?
I suspect we can't simply calibrate MOVIE mode in 60hz at a color temperature of say 7100k with Pure Cinema: OFF and then in 72hz with a color temp of 6500k with Pure CINEMA: Advanced? I just wanted confirmation as I'm pretty sure we can't.
Very good deal too !!!
