If you are using HDR passthrough, those settings might not work. 

If you are converting HDR to SDR with pixel shaders (by unchecking HDR output under pixel shaders), then those settings should still work.

If you are using a projector, you should get the best results by converting HDR to SDR anyways, so check to see if you have HDR tone mapping configured correctly to convert HDR to SDR.
