I think it's competitive to a point but not as competitive as Plat and beyond. Having the Victorious skin reward is just something to make people want to at least get there. Since they moved the Season ward skin into a new system of the Team Ranked Rewards, that already took away one reward for those in Silver and higher, so why would you want to cut down rewards on Gold? I don't think they really need to take away another.
Most of the community isn't even very competitive since it either falls into Unranked or Bronze, and Bronze has the Decay proof so that people don't fall back to nothing. So I don't really see why they should change the rewards more when they've just given a bit of help to Gold/Silver tiers.
