no
let me try it like that....
naruto received full yang from hagoromo right?
that full yang greatly empowers all of his modes...be it KSM,BSM,SM,even base mode.....
so you are reffering to his greatly boosted power in all modes which is not rikudo sage mode(at least not from my point of view)
i see we have different opinions but THE rikudo sage mode is his most powerful mode,chakra cloak with TSB,magatamas etc. and not just any mode he activates....cause if that is true then even naruto`s base is RSM
You must be registered for see images
basically we`re saying the same time,just that you`re saying his current mode is a powered down version of RSM(which it essentially is as it is BSM with full kurama+great boost of his yang chakra and is only one step below his most powerful version of chakra mode) and i am saying this is a separate mode,not yet the most powerful mode that is RSM but just below
