I have now done similar tests for NTSC on the same machine, using the TLC NTSC trick to have the colors appear on a PAL display. The results are (documented, measured, converted to PAL/YUV):
70 69.7 (102.7)
250 245.5 (278.5)
20 22.6 ( 55.6)
208 211.6 (244.6)
314 311.9 (344.9)
134 138.8 (171.8)
90 92.3 (125.3)
115 120.5 (153.5)
162 161.6 (194.6)
50 47.5 ( 80.5)
232 229.7 (262.7)
290 289.6 (322.6)
350 350.4 ( 23.4)
180 180.2 (213.2)
The dark blue color is now almost exactly as documented, unlike in the PAL case. It does not really look like blue, though. The orange is indeed different, but that could still be just random inaccuracy.
Until now, I have assumed that the NTSC colors should look the same as PAL. But the difference can be emulated, I will just need a total of 20 colormaps instead of 16 to reproduce all possible effects.
