I definitely think that was part of the goal, but Russia hasn't really revealed much so far. We now know that Russia has excellent EW capability that can disrupt western guided weapons and drones. They also showed that they have missiles that western AD can't handle.
None of this revealed much about Russian overall capability however. One thing Russia made clear is that they have very strong military industrial complex and are not at risk of running low in terms of weapons. The big surprise for everyone, including Russia, was just how effective Russian drones ended up being.
So, far we haven't seen any really advanced weapons like Su-57 or T-14 used, so Russia is definitely not playing their full hand here. Seems that they're largely just clearing out their old Soviet inventory for the most part.
