The best and most correct option for such TVs will be the IPTV set-top box on Android!!! Everything else is makeshift solutions!!!
ATTENTION! In connection with the update of the donor application RedBull, the player ott-play (FOSS and DRM) stopped loading on many Samsung TVs. For this reason, it is better to install these players on Samsungs through a widget (a computer/laptop is required). Download the archive of any player to your computer, unzip it, run the application (file with exe extension) and follow the instructions that appear on the screen:

https://forum.tv.team/files/DRM-play/DrmPlayInstallTizen.zip
Additions and clarifications to the instructions:
1) For more information about how to enter the developer's menu, you can look it up on the internet using the search tool;
2) The computer and the TV must be on the same local network, i.e., connected to the internet in the same way - both with a cable or both with Wi-Fi;
3) Press the buttons in this order: 1-OK-2-OK-3-OK-4-OK-5-OK, i.e., after selecting a digit, press OK. Note that the buttons should be pressed quickly, without pauses.

Install the player on the TV
LG
Samsung
Upload the playlist to the player https://siptv.app/mylist/index.html
a) in the MAC field, enter the MAC address of your TV;
b) the "snake" to the right of the MAC field changes the way to download the playlist, either you download the playlist and point (select) the path to it, or you provide a link (URL) to the playlist, and the device itself pulls the necessary playlist from our resource; the link to the playlist can be seen in the Playlists->Links section of your personal account, select SmartIPTV playlist and click the Copy button, the link to the playlist for this player looks like http://tv.team/pl/13/*******/playlist.m3u8 (instead of asterisks your unique access code (token)); we recommend the second way of downloading the playlist, as you won't need to download the playlist again in case of changes in the channel list;
c) in the EPG field, enter the link http://epg.team/tvteam.xml
Restart the player and watch TV.
You do not need to specify the EPG country; if you want to specify, you can choose ExUSSR for Russia.

Set up the player according to the instructions 5.5 Setting up the ott-play player.
- Player M3U IPTV (only for Samsung Tizen and LG WebOS)
https://m3u-ip.tv/
For the M3U IPTV player settings, use the Televizo playlist.
It seems that the archive in the M3U IPTV player only works on the Premium version of the player, which costs 1400 rubles.
