Are there AndroidTV devices that use ethernet and don't have WiFi capabilities?
Context: I'm developing an app and due to our already existing method of authorization I need a Mac address. It doesn't have to be currently used Mac address just a Mac address of the device. It turns out that it is rather difficult to get an ethernet Mac address using react native libraries and WiFi Mac address can be easily access. So I'm wondering if handling a case for no WiFi Mac address is worth spending time.
Whatever you're doing for authorization based on MAC address is highly discouraged.

In fact, you're pushing an method that will likely cause more issues since MAC addresses exposed to the user can change over time. Expect to change more often, even possibly randomizing in the future based on network they are attached to. In fact, Android 12 added the ability to randomize the MAC address every 24 hours.
If your app is bound to the internet, consider revokable device tokens.
