Certainly my 'Day Mode' calibration works very well on my LED compared to my CCFL for the reasons that Michael explained previously. (thanks Michael for that and your videos).
My observations are based on being compelled to have kids TV on regularly at about 4pm to 5.30pm for my grandchildren.
Previous 'sunshine' during this time using the CCFL was simply unwatchable (as far as the grandkids were concerned), not so now.
Using sunshine as a means to turn off the TV and get them to prefer outside activities has become very difficult.
Not very scientific I know but there is a remarkable difference between the 2 TV's using exactly the same D65 and 2.2 gamma.and with my LED TV in the same position as my CCFL in the room.
I suppose I am saying certain hardware 'types' appear to be more / less vulnerable to ambient light changes on the same calibrated settings.
I would love to have a dedicated viewing room but that is impossible so perhaps others like me who are amateur calibrators but must compromise ought to be looking for specific types of display that are from a visual point of view less prone to ambient light changes.
The OP suggested using D75 as an option to make his calibration more viewable, perhaps choosing a more compliant Display would be another choice?
A PJ would presumably be bottom of my 'Ambient Light Tolerance' list but how does it progress from there?
Are Plasmas better than LED's, etc..
