At least that's what I've noticed. HDR is supposed to have good lower range as well, which isn't the case with Dolby Vision on these TV sets.
I've edited the test pattern in the post a little late, here it is again:
It's FEL so you can compare HDR10 and Dolby Vision.
ok sorry for the late reply, it took me a while to check this pattern but indeed, DV black level is wrong compared to HDR10. It is very obvious in my pitch-black room. I decided to check it out after noticing the ugly raised black on ''All man kind'' on my Shield. Then I went back comparing some movie that I remembered having terrible black level when I watched them in DV (I assumed it was how they graded it) and I actually always compared brighter scenes which are easier to capture with my camera.
so on my x700, I checked Atomic Blonde Dual-layer rip. if you pause at 34sec(frame 848) the image is dark grey/black in both HDR10 and DV but you can't see the black bars at all in DV, they are elevated while in HDR10 you can clearly see the darker black bars. the DV version actually looks like a full screen 16:9 movie for a couple of frames lol .
Just to be sure the problem was not my x700, I checked All mankind P5 DV on the Shield which as I said, I noticed has elevated black too. again right in the first few seconds of episode 8, perfect black level in HDR10 but ugly raised black in DV.
Are sure this is only a problem with these TV sets because not only I'm seeing the same thing on my Vizio tv but I can also capture it with my x700 dv to HDR conversion(no c8 in the chain) which I thought was faulty because of the black level but I now think it turns out that it actually captures how the black level are messed up in DV. to me all of this sound like a major issue with DV algorithm.

* represent exactly what I'm seeing in a pitch-black room. of course, check out this comparison with all the lights off.
Atomic blonde 34sec frame 848: https://screenshotcomparison.com/comparison/12921
*again represent exactly what I'm seeing in real life. also, the difference is only very obvious in a completely dark room.
all of this is disappointing to me, a lot, I almost wish you never told me that lol ... its either a punchier/brighter image in DV with horrible black level or a darker HDR10 image with better contrast and inky black level.
