FYI. I tested with HDR movie
i do not have all the equipment and sources to test all of HDR, still experiemneting... but i will say, from what u described so far:
.. u r playing an ahem video from pc and casting to tv... questions about your pc and casting capabilities...
.. those files are ahem ripped, u never know how good or poor they are; try diff versions.. 10GB, 50GB., 90GB ones.
.. your tv... i dunno much but this strikes me... notice the use of words "supports", "compatible" and "optimizes"?
a true HDR Dolby Vision TV will not put it that way.

LG SUPER UHD TV
supports premium HDR content mastered by Dolby Vision™
and is also
compatible with generic HDR10 and HLG. LG’s Active HDR™ technology
optimizes HDR picture scene by scene for a life-like viewing experience.
http://www.lg.com/in/tvs/lg-49SJ800Tthose diff shades of dark and bright are normal with HDR videos in general.
the only way to truly test it is to use a genuine 4k HDR BD played thru a BD player to your TV.
my own experience... HDR is inherently dark, need to max out backlight, play with contrast.
if u play the better HDR files with a good player, with good player and tv settings, it can come out very nice!
