Strangely (to me) whether with TeX-engine set to xetex, luatex, or default, the 
same command is invoked
(apart from name of tmp repertory)

Running `Preview-Ghostscript' with ``/Library/TeX/texbin/rungs 
-sOutputFile\=aucxetex.prv/tmpAAVPBX/pr1-\%d.png -q -dDELAYSAFER -dNOPAUSE 
-DNOPLATFONTS -dPrinted -dTextAlphaBits\=4 -dGraphicsAlphaBits\=4 
-sDEVICE\=png16m -r240.615x252.2 -dDELAYBIND''

My gs version is 9.54

$ gs --version
9.54.0

xetex/luatex display the problem I mentioned but not default (which has "compile 
directly to PDF")

which I also get from M-! then gs --version

Best,
