Aha! My first time to hear of .dfu files. And yes, you are absolutely
correct as far as those 6 characters having definitions in the
utf8enc.dfu file, while the two lenticular brackets are not in that
file.

So perhaps the question becomes: for unicode characters that have
existing definitions in the .dfu file, how would one adapt vertical
typesetting? I am supposing that removing the definition from the
utf8enc.dfu file is not an acceptable solution.

Is it possible to force latex to read the definition in the fdx file
and overwrite whatever it had previously read from a .dfu file? I'm
afraid I still know far too little about latex and tex programming to
see exactly what issues are at stake here.

Is the setting or "fetching" of the glyph for horizontal CK is also
not under control of the CJK package but rather done by normal latex
in this case?

Best regards, Gernot
