Software support for Smart TVs still varies widely depending on the manufacturer you buy from. Much of the experience of owning a smart TV depends on the software it uses, not only on the panel. That is because features like HDR10+, Dolby Vision, and other functions need updates to work properly. Even if your TV still turns on and seems to work normally without software updates, it starts losing ground little by little. Besides apps losing support, security flaws can also happen, along with other problems that affect anyone who does not update the TV software.
