There's no pigmentation around the eyes so far. Here's an adult Naruto using regular SM, this pigmentation is clearly more extented than one presumably seen in Boruto. Plus, TSBs aren't a necessary component. Only the eyes matter, and they fit into description of initial SPSM. Even the databook entry of SPSM uses this image to display the mode, the chakra mode with TSBs is only an enhanced chakra-powered version of SPSM, but its regular version is signified only by the eyes.
