Hi DRAK,
Weirdly enough I have a partial solution, at least in BFV. I don't really consider this a solution because 1) it's not reliably reproducible and 2) it's not clear I'm actually getting the HDR experience the way it's supposed to be. But anyway, I've found that sometimes if I switch my resolution / refresh rate in game repeatedly while I'm in the practice range then I get different performance on HDR, to the point where it does seem to be at least a marginal improvement over SDR. Typically I'm switching back and forth from 2560x1440 at 144Hz to 1920x1080 at either 60Hz or 144 Hz. I'm doing this entirely randomly, and I haven't found any particular sequence of these switches that works. I have a hunch that sometimes when you switch resolution a different bit of software/firmware takes control, as it were, and then you get a different experience. It seems to match up with my understanding of the problem which is that there are software communication issues that cause different bits of software (whether the OS, graphics drivers, the game, or whatever else) to try to take control over whether HDR is displayed. Conflicts then result in an unintended experience.
Anyway, that's my partial solution and two-cents best guess as to the broad outlines of the problem. Hope it helps, or at least keeps you from going nuts in frustration.

As a resume for you to check:
-samsung in "game console" mode + "game mode" on (deactivates virtual Samsung HDR) + UHD ON, on correct hdmi port
-ddu and reinstall last nvidia drivers (reset pc)
-activates windows HDR + force in nvidia panel ycbcr10/12bits (samsung should go auto into ST.X gamma profile from BT.X, check it in TV picture/expert menu)
-go bfv switch hdr on, go to main screen and check osd volume (should looks wrong as always)
-go options again and switch off hdr, check graphics and test with osd volume (HDR should looks correctly now, insane..)
Let me knowo your results :P
Have a great day!
PS: ill extend after comes from work =))
Update:
Well.. i just bought Battlefield 1 & Metro Exodus for try another games with HDR:
1º Battlefield 1 have the same problem as Battlefield V, HDR not kicks in properly, and when go around (tricky) to activate it, it looks horrible with non proper gamma correction
2º Metro Exodus just works directly with 0 problems, as intended, btw it looks awesome...
So in the end it seems like an EA problem, its not normal that all HDR content that i try works perfectly except for Battlefield V & 1, and im not the only one, its a general bug.
Shame i expended +2.000 euro in new pc thinking in play BFV at 100%, and now i have to expend nearly +100 euro more in 2 more games just fot be sure that its an EA problem... too bad =((
