Is HDR Mode on 4K HDR Blu Rays Suppose to make the Image Dark ?

[Foxticious]

So I have a 4K HDR Sony TV And Xbox One S, I played Salt Movie with Angelina Jolie which is 4K HDR. As soon as the blu ray loads it goes into HDR Mode and the screen is very dark ???

I dont know what model TV you have, but I have noticed that HDR can look dark in may situation - but I guess this is overcome on high-end models where the brightness of the TV (nits) is higher than on mid-range and budget HDR models, as well as things like full array local dimming etc on high end models.
