I don't think that is the case. Check out page 100 of the manual. Operation Type only affects the display of shutter angle and time code. Now it does affect the ability to use certain functions, page 47, including Interval.
When I setup for Interval recording I still have CineGamma enabled in my menu. I do not see a change in the image when I switch between FILM CAM and VIDEO CAM which is noticeable when the Gamma settings change. This is different from the Varicam which has a different Gamma setup for these two similar settings. That may be where the confusion originates.
