Can you test this function:

(defun org-table--comma-as-decimal-sep ()
  "Return nil or 2 if separator is dot or comma respectively."
  (string-search "," (format "%f" 10)))

To test I am using:
$ LANG=de_DE.UTF-8 emacs -Q

But I am getting this as warning:
(process:1787): Gtk-WARNING **: 15:40:49.375: Locale not supported by C library.
        Using the fallback 'C' locale.
