Respecting that patch text file, from this reference: http://atariage.com/forums/topic/95498-7800-color-palette-in-mess/?p=1174461
We have come a considerable way with Atari 7800 palette understanding since 2006.

The entire thread is worth the read, IMHO.
Majority of PAL units, even after warm-up demonstrate a COOL palette.
Majority of NTSC units after warm-up demonstrate a HOT palette.
Ideally, displays would be calibrated for brightness and contrast per the CPS 7800 Diagnostic Cart.
Colors should reflect how they would appear under a CRT as that was the target display device of developers and how label interpretation for the hues was derived back in the day.
