Hi Andy,
please open an issue in the Gimp issue tracker and attach an example file:
https://gitlab.gnome.org/GNOME/gimp/issues
Some scanners create 4-channel/12bit encodedimages. Then the 4th channel
is an IR channel that is useful for reducing dust.
Regards,
Tobias

I try scanning to 48bit (16 bit per channel) TIFF with VueScan, but GIMP
reads
it wrong, forwarding the data partially to alpha-channel. Probably, it is
interpreting 3-channel/16bit image as 4-channel/12bit encoded.
If not, I have no Idea where that 4-th alpha channel comes from (it is not
blank, but filled with some ghost from original image). So probably other
channels are also damaged.
There are also error messages appear:
"Incompatible type for 'RichTIFFIPTC'; tag ignored"
and
"Alpha channel type not defined for file C:\...\.tiff. Assuming alpha is
not
premultiplied."
Is there a way to read 3-channel 48-bit TIFFs to GIMP correctly?
