As per Tim's comments. Whether the material you watch is FILM source DVD, HD-DVD, BD or broadcast it is VIDEO. ie the format is a VIDEO format. The material has been transferred to that format with D65 and Gamma 2.2 as the target playback medium. It is true that some folk prefer to play back video material with a 2.5 gamma as they feel it has a more "film like" response but it's not correct. You need to understand that while the material you watch may have been recorded with film it is NOT film. It has been graded and coloured for our VIDEO systems.

It should also be noted that a PRESET in a display device is not going to give you the correct settings for your room/equipment combination. I have measured and calibrated 100's of displays. Only one ever measured very very close to D65 out of the box. It's gamma was shot though and once the crushed white detail was fixed and gamma was fixed it was no longer D65...and I then had to calibrate that aspect.


Hope this is a little use.
