Which is better for a bright living room?

The TCL QM6K. Its Mini LED backlight pushes higher full-screen brightness, while the LG C6's OLED panel is dimmer across the whole screen. The LG wins on black level in a dark room.

Is the LG C6 worth the extra $802?

Only if you watch in a dark room or sit off to the side. The C6 gives per-pixel blacks, wide viewing angles and 0.1ms gaming response. The QM6K covers brightness, 144Hz and sound for far less.

Which is better for gaming?

The LG C6 for response time and sync features: 0.1ms, VRR, G-Sync and FreeSync Premium. The TCL QM6K runs a 144Hz native panel with Game Accelerator 288, which suits fast PC play, but its pixel response is slower.

The TCL QM6K has no burn-in risk, so it is the safer long-term pick for news tickers, sports bars and static logos. OLED pixels dim unevenly over years of static content; the C6 needs varied viewing to avoid it.

Do both support Dolby Vision and Dolby Atmos?

The LG C6 supports both. The TCL QM6K lists Dolby Atmos and DTS Virtual:X for sound, but its HDR support is listed as HDR10 and HDR10+ rather than Dolby Vision.
