The thing with HDR stuff requiring a lower CRF for the same quality level is that the image is very flat so the encoder will give it much less bits compared to SDR at the same CRF. I use settings close to --preset slower and CRF 15 + qcomp 0.7 for 1440p and CRF 16 + qcomp 0.7 for 1080p encodes with HDR.
