You're quiet right - if some shader will give same quality as VLC it'll be appreciated.
Some more exact in case of HLG ARIB STD-B67 instead of yours 2020 on my own.
You can download libplacebo from VLC and three sample videos from my posts above.

I agree, but again VLC quality of showing HLG (ARIB STD-B67) on BT.709 monitors and TVsets is quiet enough.
