Currently, there is only a size limit for data stored to local user defaults on tvOS, which posts a warning notification when user defaults storage reaches 512kB in size, and terminates apps when user defaults storage reaches 1MB in size.
For ubiquitous defaults, the limit depends on the logged in iCloud user.
