I am able to reproduce this on Win10 using a three-channel .lif XYZ file after updating Fiji or ImageJ to the latest build.
But it works fine for both on older versions of ij.
Same status as that described on Wrong LUTs when opening .lif files from Leica with bioformats.
ImageJ before updating: 1.51j ; after updating: 1.51t
Fiji(ij) downgrade to 1.51i ; after updating: 1.51t
bio-formats package: 5.7.2
Hopefully, this info could give Wayne some idea.
Happy New Year!
