Last month , Apple introduced thenew Apple TVand with it , a new vividness calibration feature in tvOS 14.5 for its stream boxes . The way it work is you bind a compatible iPhone against the screenland as it flashes through a serial of coloring material and then voila — you’re supposed to get a properly balanced television in a crack - easy way . Turns out , it might not be that simple .
Professional TV calibrator Vincent Teoh posted aYouTube video(via9to5 Mac ) that puts the new colour residuum feature through its paces . Teoh used two first - gen Apple TV 4 K boxes and an iPhone 12 Pro to see whether the feature improved coloring material truth on the LG C9 OLED TV , Samsung ’s Q80 T QLED television , Sony ’s XH90 ( X900H ) LED LCD , and a Sony BVM - HX310 reference monitoring equipment worth around $ 42,000 . Some of the tweaks are n’t that noticeable to a layman ’s eye , but Teoh also measured the results with professional standardization tools .
In Teoh ’s testing , Apple ’s standardisation feature delivered mixed results , and in others , actually made vividness truth worse . For deterrent example , with the Samsung TV , the calibration feature article did improve color accuracy but also end up making the overall icon bluer in tone . It also shifted the Sony ’s image to a ice chest tone while worsening overall color accuracy . The best results came from the LG television receiver , in which the feature improve color truth without dislodge the image to a ice chest tone . Meanwhile , the feature article should ’ve left the $ 42,000 character varan alone . Instead it “ set ” the image to an inaccurate one , which defeats the whole purpose of the lineament . Overall , it appears that Apple ’s lineament use a bluer snowy point than the standard D65 bloodless point used by filmmakers and other Divine .

Another outlet is what out - of - the - box preset manner you ’re tend the calibration characteristic on . If you ’re using the most accurate one for your particular TV , you might not notice too much of a modification . But if you ’re calibrating from a much more inaccurate setting , like Standard , Teoh set up Apple ’s feature deliver more substantial improvements — but at the expense of paradigm quality . Color accuracy was better , the feature stop up over-correct , resulting in posterization . ( Posterization is when rather of a legato changeover between people of colour gradients , you end up with visible bands . ) The characteristic also performed differently on OLEDs versus lead LCDs . These final result also line up withCNet ’s examination , which found that the feature sometimes improved an image and color truth . Other times , not so much .
Or in other words , while the Apple TV 4 K ’s color standardization feature works and is crack simple to use , it ’s not a switch forchoosing the correct preset picture settingor having a basic cognition ofwhat these configurations intend . ( For most people , that ’s exit to be Cinema or Movie . ) Once you ’ve done that , you’re able to try the color balance feature , see how it agitate the ikon , and go from there . Sorry folks , but one - occlusion solutions are always exit to be too dependable to be dependable .
