The star version produces a command that is not "long", meaning that star-version newcommands cannot take arguments that contain a \par. In your example, there is no difference, since \captionformat takes zero arguments. If, for example, \newcommand*{\captionformat}[1]{ -#1- }, then \captionformat{x\par x} would produce an error. – Steven B. Segletes Jul 14 '22 at 03:28
@StevenB.Segletes, thank you very much! – Intolighter Jul 14 '22 at 03:59
Side note for this command in particular you can find documentation in "the LaTeX unofficial reference manual" – user202729 Jul 14 '22 at 04:14
(or macros - what does an asterisk (*) character do in a renewcommand? - TeX - LaTeX Stack Exchange for one specific to renewcommand) – user202729 Jul 14 '22 at 04:15
