Amazon 55" Mini-LED TV

Amazon's Mini-LED tier of the Ember line: 512 dimming zones (denser than the entry Ember QLED above), over a billion colors, Dolby Vision IQ and HDR10+ Adaptive. It's rated AMD FreeSync Premium Pro at 144Hz, which Amazon positions as its best Fire TV for gaming, and Fire TV Intelligent Picture adjusts settings scene-to-scene automatically.
