I don’t see how “slightly different” could support the argument that things were effectively better at the time citizens were put into camps. The legal system supported a racist policy by “6-3 ruling about their constitutionality”. Furthermore:

internment camps were effectively ended by the the supreme Court the next year.

No. It was over two years before the order was suspended and the last of the camps shut down. The order was not officially terminated until 1976!

Over the spring of 1942, General John L. DeWitt issued Western Defense Command orders for Japanese Americans to present themselves for removal. In December 1944, President Roosevelt suspended Executive Order 9066, forced to do so by the Supreme Court decision Ex parte Endo. Detainees were released, often to resettlement facilities and temporary housing, and the camps were shut down by 1946.
