Hi,
I assume that ImageMagick just reports the values from the tiff image
pixels as floating-point.
The encodings from the ICC standard are not directly relevant for these
values.
There is more than one encoding for tiff images: ICCLab and CIELab, see
e.g.
https://developer.adobe.com/content/dam/udp/en/open/standards/tiff/TIFFphotoshop.pdf
on page 12 and 13. See also the discussion in this list,

Best regards,
Hanno
