Königsberg was occupied by soviet union in 1945 and renamed Kaliningrad. It remains as a peculiar Russian enclave. Why was the city never returned to its rightful owners?

Other areas claimed independence when soviet union collapsed. Why was kaliningrad never returned to the original owners? The area is nowhere near Russia and was never historically part of Russia. Similarly, the case of Gibraltar has been an ongoing issue between Spain and England. Has this also been the case between Poland and Russia? Has there been demands of ending the occupation of Königsberg or is it accepted as belonging to Russia?
