Sega Saturn PAL - Blueish tint after 60Hz Mod

I did the switchless region/50-60Hz mod on 2 of my Saturns, everything works perfectly, except that the colors are a bit off now on my LCD-TV's using the Scart connector. Strange thing, the 3rd unmodded PAL Saturn displays the colors spot on, using the same cables on the same LCD's.

If I hook it up to my old CRT over Scart, all 3 of my Saturn's, modded and unmodded, are displaying the correct colors.

What I mean with the colors are off .. they're all there R+G+B, but it looks like the color temperature is way off towards the cold end, it's most pronounced in the white areas, hard to explain. As if the white balance is wrong, if that makes sense?

At first I've thought it had something to do with PAL consoles running in 60Hz NTSC, but the second Saturn was actually a Japanese NTSC-J Model 2 Saturn, which should have no issues outputting correct NTSC signals ...

Could someone explain to me what's going on there?
