You can identify them using the user agent string.

roku devices has a user-agent string something like this

Mozilla/5.0 (compatible; U; NETFLIX) AppleWebKit/533.3 (KHTML, like Gecko) Qt/4.7.0 Safari/533.3 Netflix/3.2 (DEVTYPE=RKU-42XXX-; CERTVER=0) QtWebKit/2.2, Roku 3/7.0 (Roku, 4200X, Wireless)

you can access the user agent string with this in js

is_a_roku =  function (){
   let user_agent = navigator.userAgent;
   return user_agent.indexOf("Roku") != -1
}
