Samsung QN90B QLED vs Samsung QN85C/QN85CD QLED

The Samsung QN90B QLED is better than the Samsung QN85C. The QN90B gets much brighter than the QN85C, but in practice, this isn't always noticeable as most content just isn't mastered to take advantage of such high brightness levels. The QN85C is the more accurate TV of the two; it respects the content creator's intent well. However, the QN90B is the more colorful TV, with a wider color gamut and better color volume, and it has much better reflection handling, although it does have some rainbow smearing.
