Yes, -127 to +127.
« CIE files specifications »? There is no such thing.
CIE measurements can be saved in any format.
But for the purpose of color management, things revolve around the
“CGATS” standard.
It’s a text file format with fields documenting the Illuminant, Observer
and what the data represents.
There’s usually “device” data, CMYK or RGB, and “CIE” data, XYZ, Lab,
spectral, density, Lch, even some statistics like standard deviation
although that’s mostly found in IT8.7/1 or 2.
