As far as I know there is no way to determine whether a channel has bits rewards emotes (unique and permanent emotes unlocked by spending 1K bits, 5K bits, 10K bits, etc. in that channel) unless the owner or someone with the emote uses it in chat. It apparently can't be looked up in the bits menu for the channel or anywhere else.

I'm not referring to cheer emotes, or to custom bit badges for certain levels that appear next to your username when in that channel, but to permanent emotes that can be used anywhere on Twitch, even if you don't subscribe to the channel in question. The emotes are tied to bits spent, not to subscriber status.

Is there a way to know whether a channel has bits rewards emotes without waiting for them to be used or asking the owner of the channel? It would be very useful for those of us who follow dozens of channels but aren't sure which of them have them and which don't have them. Thanks!
