Welcome to the Roku Community, @KeithB1.
Thanks for sharing your thoughts; we value your feedback as our valued customer. We understand you are inquiring about the Roku Backdrops feature on your Roku device.
We don't have any information about when the backdrops available will be device-specific rather than account-specific. Please know that Roku is constantly striving to improve the Roku streaming experience.
We will forward your feedback to the appropriate team for their review. Once again, thank you for your input; it is greatly appreciated.
Thanks,
Chel
