Are you not perhaps confusing the regular tone mapping the TV does with the dynamic option?Yeah I am starting to think it's not very good either. So I am considering getting an Panny UB820. The trouble is a lot of people recommend using both the UB820's HDR Optimizer (which is just its tone mapping as far as I know) AND the TVs. But I am trying to avoid using the TVs as, as you mentioned, it's results aren't always great.
The TV takes it from there and tone maps down to 700 nits.However if I just use the players tone mapping and it tone maps down to 1000, but my TV is only capable of around 800, then dont I simply lose information from 800-1000?
With OLED selected the UB820 maps all output to a more digestible 1000 nits, your TV takes it from there. The TV maps down to 700 nits, this happens regardless, what DTM does is manipulate the curve as its algorithm dictates. Just leave it off and let the UB820 and LG tone map in tandem for the best image. That's the benefit, the UB820 does the heavy lifting making light work for the LG.That is why I was wondering what the LG's DTM maps down to. I always figured it was down to what the TV can handle, say 800. But maybe it only goes down to 1000. In which case, both devices tone map down to a point and would make choosing one or the other earlier and would really (In my mind) make double tone mapping pointless.
