HLG certainly does not look "normal" on a reference monitor in SDR mode (BVM-X300). You can however crank the brightness and contrast and get an acceptable picture. That's what the "backwards-compatibility" of HLG gets you. That is not the case with S-Log3 and PQ.
Now, once you add 2020 to the mix, the backwards compatibility claims gets a little more dubious. 2020 on a 709 monitor is quite desaturated.
And HLG certainly will blow out an SDR display when you push the iris. It's HDR. You still need to do some sort of knee/tonemapping/clipping to convert to SDR.
Whether HLG or PQ is easier to convert to SDR, I guess it's about the same. The problem is fundamentally the same in both cases (squeezing HDR into SDR).
