Is is possible to download Roon app on to smart TV?

Is it possible to download the Roon app on my Sony smart TV or LG smart TV?
I have firestick. It would be nice to be able to do so.

No it’s not. It does not lend its self to a remote it’s designed around touch and a mouse and keyboard.

My LG soundbar has Google Chromecast built in so I stream Roon to it. Chromecast only works for audio streaming. I can’t use it, via the HDTV, as a Roon display. By the way, although Chromecast only steams up to 24bit/48kHz, which, to me at least, is the perfect compromise for digital audio resolution, nonetheless, it sounds delightful.
