Apple announced a bevy of new upgrades for the iPad Pro and iMac. Moreover, the Apple TV was not left out of the mix too as it received a boatload of new features as well. While the set-top box itself is more or less the same as its predecessor, the Apple TV Remote received a complete design overhaul. It now boasts an all-metal build with numerous additions. One of the major Apple TV 4K additions that Apple touted is an iPhone-based color balance feature. If you are not sure what it is, scroll down to see more details.

The new iPhone-based color balance feature will work on all Apple TV models that launched in 2015 or later. The feature will be made available with the release of iOS 14.5 and tvOS 14.5 next week. The new color balance feature in Apple TV 4K works in a pretty neat fashion. You will be allowed to hold your iPhone with Face ID in the front of your television set to adjust the color of the display.
