The correct method for comparing color rendition is as follows.

It requires a modulator and a box, usually a Blu-Ray player, that will
play from memory sticks.

1) Obtain suitable jpg file of subjects that illustrate want you think matters.

2) copy those to your memory stick.

3) play them to your TV.

4) take pictures of the TV

5) transfer the pictures to the computer the files came from

6) one at a time, open the pictures of the TV in a photo editor
on the computer. At the same time, have the picture showing on the TV,
set just as it was when taking the picture.

7) edit the photo on the computer until it looks just like the TV
(that is, the image on the computer screen looks like the TV)

8) save the edit picture.

You then upload both the original picture you played on your TV
and the edited picture you took off the TV

Because you edit the picture of the TV on the computer to match the TV,
if you show the original and the TV picture on the same computer,
you will see the difference the TV made. This will also be true
of doing the comparison on ANY computer since you will have the
two files to compare.

There are three pairs of pictures made using this method

One of them is three bicycles, another is purple flowers.

I've attached images of a standard test pic.
