The next rung down on the quality ladder is manufacturer-provided profiles.

Since I started reading about color management in Linux (a few years ago, IIRC when somebody released 'xicc', who could preload a profile and then Eog could use it) I never found a good manufacturer profile.

Maybe I've got something wrong in my eyes or I'm ruined by years without color management, because all the profiles I tried (for LCDs by Samsung, Philips, Acer and Sony) changed the standard RGB blue in something that I could only describe as "violet" or plain white in yellowish white, so in the end I usually disable CM again and make do without it.

There could be something wrong with hardware you've used but the mostly likely explanation is that you are used to systems running at a much bluer white point than exists in nature. OEM's tend to set the default white point on their hardware to a very blue 6500 or 7500K because it looks better in environments lit with fluorescent lights. People don't realize how distorted it is until they compare it against real world imagery or a properly calibrated display. A properly calibrated display will feel like the whites are yellow hued to start with. After a while of allowing your eyes to adjust when you look at an uncalibrated display you will be astounded how blue the whites are.

My experience is that the manufacturer provided ICC files aren't worth much against spectrometer calibrated displays. And color calibration spectrometers aren't very expensive.
