Color matching

Hello,

I've been trying to get an LCD TV panel (Panel A) at its native
setting to match the color temperature and profile of another
different TV panel (reference). I have access and means to control the
color LUTs for the panel (Panel A).

I also have been able to get Lvxy measurements for both panels for R,
G and B color planes for all intensity values (0-255). However,
adjustments to color, or gamma that might have been performed on the
reference panel are unknown.

With these factors, i have the following questions...

1) Do i have sufficient information to be able to match panel A to the
reference panel both in terms of the color temperature as well as
color shifts?

2) If so, how do i go about it?
I have tried to match the white point of the panels by using the
Bradford transformation, but i'm not sure if i;m using that correctly
or if that is the way to go. Morover i'm not sure of the reference
illuminant or the RGB space being used...

3) In addition if i just want to reach a reference color temp, say
D65, how would i go about it?

I would appreciate it a lot if someone would educate me on this. The
documents and literature i've been referring to on this have just
added to the confusion. I hear about Chromatic Adaptation, Von Kries
and all that, but i'm not sure if those apply to the problem at hand.

Thanks
SR
