OK, I did some experimenting.
I made a swatch in Illustrator CC, with Pantones define as spot LAB values.
I saved this as an EPS and imported it onto a new Reference Page in Frame 12.
Arnis, it works PERFECTLY in CYMK mode! The colours in the swatch all appear in the my Frame colour definitions, and if I examine their CYMK values, they match exactly the CYMK equivalents Illustrator uses if I take the Pantone out of spot LAB mode and view the CYMK equivalent. Given that Frame doesn't support LAB, we can't really ask for better.
However, it all goes belly up in RGB mode
As per the definitions in the Frame11 Maker.ini reference, in my maker.ini [Preferences] section, I have GetLibraryColorRGBFromCMYK=None, which is meant to "Display and print the RGB values from the library color description."
However Frame12 isn't doing this - it is using its own bogus algorithm to convert the CYMK value to RGB, the same broken behaviour we saw in this thread here https://forums.adobe.com/thread/1485020
when text colour in CHM output was all wrong.
For instance, compare this "Spruce Green" (Pantone 355C) - in Illustrator (right hand side), if I take it out of Spot LAB mode and ask for an RGB equivalent, I get 0-148-77.
Frame obfuscates this a little by expressing the values as percentages, but converting it to values out of 255, we get 0-220-0 (that lurid lime green colour)

Clik here to view.
Now I don't think I'm being unreasonable in asking how on EARTH is that supposed to be a good equivalent to the original Pantone?!? It's zeroed the blue channel!!! Truely bizarre.
