Roku tv and device models

It sounds like you might carry more clout with Roku than customers. I.e., it sounds like you develop something. Maybe contact someone in the developer program.

It's obvious the information exists. There must be a database of Roku internal model # to tv-maker model #. It's just a matter of finding someone who can run a query to get the cross-reference. Customer Service seems more like a firewall to protect the insiders from customers. So, you may be pursuing the topic in the wrong place. (I'd suggest your developing for the wrong smart tv platform. But, time will tell.).

Anyway, your quandry is what customers have expressed too. Roku doesn't seem to think beyond its own experience. It exists with the internal model numbers, and that's "good enough." They don't have empathy for why anyone would want to know which brand models are an internal model. It's a nothingburger to them. It's like we're talking martian.
