Natural vs colorful picture
The two TVs are really very similar. That means, which one is really better is often a matter of taste.
Even in terms of gaming, the differences are small. The variable refresh rate will still come with the Sony X85J. In the meantime, you can also say that with more certainty, since the XH90 from last year now already has the beta update for VRR and since Sony has also confirmed on request that the X85J will also get more features for Playstation 5, such as “Auto HDR Tone Mapping”, in addition to the Bravia XR models, starting with the X90J.
On the other hand, the Q70A doesn’t have Dolby VisionDynamic HDR-format with a color depth of up to 12 Bits and Mastering of up to 10,000 Nits, which you would have with the Xbox Series X, for example, but you have to be fair enough to say that the HDRHigh Dynamic Range – image/video with more dynamic range (contrast range) performance of both TVs is limited anyway.
The differences in color space coverage or contrast will hardly be noticed by anyone without a direct comparison. This means that you should ultimately decide whether you prefer a natural or a bright, colorful picture.
