Well of course the modes would have differences. Senjutsu chakra reacts with people in different ways. Some people are allergic to peanuts, and some aren't. Same stimulus, different reactions. Jugo's cells have a biological component that reacts with senjutsu chakra in its own way. Naruto and jiraiya are both toad sages but look at the subtle differences between them based on the mastery. Mastery and biology and the specific contract you use to gain sage transformation or sage mode all impact whether you are an actual sage, how it functions, and how it looks. But the source is all the same, nature energy melding with mental and physical energies. Different paths, different changes, different abilities can be involved, but the effect in combat overall is the same, senjutsu enhanced techniques. Now, obito and madara gained ridoku senjutsu by absorbing the juubi.Six paths senjutsu comes with the package. The juubi chakra has an inherent component to it that allows the host to use six paths senjutsu chakra, so I liken it to the "contract" you enter by absorbing the juubi.

Even if hagoromo gave naruto the mode and it doesn't depend on the bijuu at all, you still have to explain why he lacks TSO when he uses the mode without his chakra cloak. I think it's clear that the bijuu chakra inside of naruto was given a special key by hagoromo so that he could recreate the juubi chakra, giving him the same abilities as madara and obito.

Also, I recall naruto asking shukaku to give him magnet style chakra for his sealing rasengan, and that was while he was specifically using all the bijuu chakra for his cloak. So it seems that requesting specific bijuu chakra is dependent from using their general chakra pool. I also recall he did the same thing when he made the 9 bijuu rasenshuriken against kaguya.

So, it's still possible he was gathering ridoku senjutsu chakra despite his request for specific lava chakra.
