No. The mechanics are identical to any other player: the app sends your login to the provider's server and downloads the current channel list, formatted as an M3U playlist or pulled through an Xtream Codes connection. What changes on a smart TV is the hardware running underneath the app. Built-in smart TV operating systems, including Android TV on some sets, generally have less processing power and memory than a dedicated Firestick or Apple TV box, which is worth knowing before you blame the channel list itself for slow performance rather than the hardware underneath it.

A player app holds the full visible list in memory for as long as it's open, and that memory use scales with how many channels are shown. On a smart TV with tighter hardware limits, apps commonly start to lag once the list passes roughly 18,000 visible channels — sometimes sooner than the same list would on a more powerful streaming box. Hiding categories you don't watch in the app's settings reduces what it has to hold in memory, which is a genuine fix here rather than a workaround, and it usually takes less than a minute to do inside the app's settings menu.

Favorite the channels you actually watch before doing anything else — this cuts a list running into the tens of thousands down to something you can navigate with the remote in a few clicks. Set the program guide, or EPG, next, since it shows what's airing on each channel and saves you from checking one at a time. Hide unused categories last, once you know which groups you never touch, so you're trimming based on real use rather than guessing, and revisit that list every few weeks as your viewing habits change.
