I'm new to android TV (Pie, TCL), but this look like a glitch that doesn't show up anywhere else on the internet. Which is strange since it's quite inconvenient. After "calibrating" the image on the tv, and installing some different video players like VLC and MX player, or Archos, the image quality was unaffected by any of the presets when playing movies from a memory stick through those players i mentioned. Pretty much every setting except brightness, doesn't produce any change to the picture. I went through apps permissions and nothing there made a difference.
Playing the same movies through the default player works just fine, for every setting in the TV menu. Just not through the players that I installed.
