To measure this, you need measurement equipment. For example, here are the greyscale tracking of 7 different ST60s prior to being calibrated by a professional. Plugging post-calibration settings from any one of these TVs will certainly change how your own TV looks, but it won't necessarily be "fixed," it will only look different than before. And when you try multiple settings, you are just trying multiple random number sets to see if anything seems to look better. If that's what you want to do, that's perfectly fine. Just understand what you are doing and the science behind it.
You may notice something going very wrong, such as appearing very red, indicating that you may have started with a very red picture and are using settings that are correcting a lack of red, for example. But other than that, you're just randomizing numbers until they look good. That can be fine, if you're talking changing up gamma 2.4~2.2, or changing contrast/brightness. But when you get into the gamma IRE for brightness and R/G/B balance it's all random unless you are measuring it with something.
Additionally, unless you matched up your two picture mode settings to look the same prior to inputting all of the new settings, there are likely inherent differences built into your Pro 2 and preferred mode. If you did this beforehand, great.
Point 2 -- Whatever you want to do is perfectly fine. But your comment proves the point that it takes time to get used to how an accurate picture should look. You can cycle between the Cools, Neutral and Warms, and depending on which way you go, the previous setting will look too blue or yellow.
And my point about watching and judging neutral material that doesn't have color bias, such as the skin tone and fruit/nature pictures on the Disney WOW disc is exactly because that material is neutral. When you watch any TV show or movie, it has been touched up and color corrected in some way. The color palette between CSI Miami and Mad Men and Law and Order is very different. Every different section or part of LOTR has a different color hue. You even get color differences due to cameras and lighting between Leno, Letterman, Kimmel, and Fallon. Even different sporting events because of natural vs indoor/night lighting, cameras, etc. So it is very hard to look at any of those and separate your display being too much "something" from the nuances of the source material. You said that after 2 hours the settings (particularly the Warm 2) started to seem yellowish. That could very well be the source material you are watching, combined with the random detailed picture settings you are using that could be pushing the picture more yellow.
If you only care about how something looks without caring what is correct or accurate, and without bothering to give yourself time to adjust to accurate color temp, etc., it makes me wonder why in the world you are bothering with plugging in other people's settings into your TV. In that case, why not use a test disc like Disney WOW to set the settings on your own to look pleasing to your own eyes?
What you do is up to you, but remember you're on the AV Science forums and what that actually means. Don't call your thread "calibration" if you have no intention of calibrating (measuring properly and setting the to correct picture settings for an accurate picture). What you're doing is tweaking the picture to something specific that you like, purposely going away from an accurate picture.
