To be honest, if you thought HDR in the absence of FALD was ever going to hold a candle to a high end screen with it, then I would suggest you didn't do your research. This is a no-brainer, and you basically shouldn't have even looked at the difference lol!
Outside of the £1800 4K 27" models, I think every PC monitor with HDR is a gimmick. Even those ones weren't perfect.
Actually, your TV doesn't have FALD... it's just direct lit with local dimming. But that just highlights how much of a gimmick Samsung's solution is.
When you have horizontal and vertical zones you have FALD, but the difference is, how many you have. I thought I have on my Sony 48, but somewhere I saw that it has propably only 35. And yeah, that´s the big difference in comparision with other high end Screens with 350+. That´s propably the reason about this new Samsung model, why we did´t see any professional reviews yet, cause everybody was expecting FALD togehter with HDR1000 on this new upgrade of chg9
