I'm not sure about 60PV250 but on the 60PV450 yes it does display 24fps properly. You can verify by switching 24fps output on your BluRay player on and off. Then pop in a BluRay with 24fps content and watch scrolling ending credits or any across screen pans. You should see a difference. 24fps' goal isn't to smooth out the pan, it's just to display it accurately without modification.
Also when testing for this, you should set the display to 'just scan.' This will enable 1-to-1 pixel mapping making detection of the difference easier during the scrolling credits.
