Is SuperRare decentralized?

Excuse me, could you please clarify for me if SuperRare is indeed a decentralized platform? I've been reading up on the topic and there seems to be some debate surrounding its decentralization. Some sources indicate that it operates on a blockchain, which inherently suggests decentralization, while others mention that there are certain aspects of its governance or operations that might lean towards a more centralized model. I'd appreciate it if you could shed some light on this matter and help me understand the true nature of SuperRare's decentralization.
