>Desaturation comes form BT.2020, not HLG.

No. Neither BT.2020 ncl matrix, nor BT.2020 primaries can really do that. It is the PQ or HLG transfer (which is what HDR is) that affects the picture. That can be very simply checked in mpv that can override matrix, transfer, range and primaries.

>EURO2020 HLG content looks ok, as it was designed to looks reasonably well on SDR devices.

Actually HLG was designed to look well on SDR devices.
