I was bored so looked up the side by side comparison between X90J vs X95J on Rtings.

The Sony X95J is slightly better than the Sony X90J. The X95J has much better reflection handling, better viewing angles, and a better local dimming feature. The X95J is also much brighter, and small highlights stand out better in HDR. The X90J, on the other hand, has better native contrast and better black uniformity, with less cloudiness in dark scenes.
