Hi Julian,
We have an expensive TV brand Loewe they are very good picture,but still need calibration for what I saw in our shop.
First we get the Loewe Compose LCD and was working with Loewe demo, then came the new Loewe LCD LED working with same picture was total differed color.
We have the Bose Video Wave the picture it is too bright and Bose was saying that this TV is calibrate by ISF for me its not true.
What I am saying is that all TV need calibration when I have the gear I have lot work to do in our shop.
