The test builds are not for the faint of heart, especially right now, but, the quality of HDR to SDR in the latest test builds is astounding. HSTM (tm) is an amazing dynamic tone mapping algorithm. There's a few users that have posted their settings along with the latest curve parameters. See if any are close to what your display is capable of in SDR and start there if you're willing to accept that it's very much a test build. Most of us are using it to watch movies at this point but it requires more setup than a final build will.
