there is a full (plain TeX) example and screenshots in a (non)answer
on stackexchange
http://tex.stackexchange.com/a/354485
but in brief:
\left| T \right|
has a kern between the T and the right hand | matching the kern in |T|
if tfm fonts are used in luatex or xetex or pdftex
but if Opentype Latin modern is used
xetex shows the kern but luatex has no kern once \right or \Uright are
used, but does still show the kern with |T|.
I'm not sure if this is a luatex or luaotfload issue?
