After calibration, the colour reproduction in SDR content on the LG NANO82T is very good. The white balance has been effectively improved, resulting in natural and balanced shades across various scenes. The gamma has also been adjusted, providing a more precise rendering of details both in shadows and bright parts of the image. Thanks to these adjustments, the television performs excellently in everyday use, offering solid colour quality and clear, well-balanced images in SDR mode.
However, in the case of HDR content, the situation is worse. The television does not support a wide colour gamut, limiting the depth and richness of colours that HDR can offer. The EOTF curve deviates from the ideal, leading to excessive accentuation of details in bright parts of the image. Unfortunately, this results in significant colour reproduction errors, as confirmed by tests on the Colour Checker. The low brightness level of the panel further negatively impacts the quality of HDR images, causing dynamic range effects to not be fully realised, and colours to appear washed out.
The television has significantly improved after calibration, especially in SDR content. The improvement in white balance and gamma has greatly enhanced image quality, providing a more natural and coherent colour reproduction. Compared to the pre-calibration state, the difference is noticeable, and the television now offers better performance in everyday use, particularly in the standard dynamic range.
After calibration, the situation changed dramatically. We managed to adjust the white balance so that entire scenes began to look more natural, and the image gained cohesion and elegance. In HDR, we finally got rid of that unwanted clipping effect that had previously marred some shots. Suddenly, it turned out that the Bravia 5 can extract significantly more from films than the “out of the box” impression suggested. Indeed, if we look at the graphs and compare them with the patterns, we can see that the beginning of the EOTF curve slightly deviates from the reference line. However, this is not so much a calibration error as it is a natural limitation of Mini-LED technology, which cannot be bypassed. Sony, instead of clinging to perfect black, prefers to prioritise the visibility of details – and in practice, it's hard to disagree with that. We would rather see the texture of the material on the screen than a pitch-black blob where all nuances are lost.
The calibration itself was truly beneficial. After about an hour spent on the settings, we felt that the image resembled that from the best cinema halls – of course on a home scale, but with the same sense of quality and refinement. And in such moments, we remember why we like Sony televisions: because when we fine-tune them, they can reward us with an image that captivates for long hours.
