The Xiaomi Mi TV 4S 65" L65M5-5ASP is great value.
But if I'm not wrong, the Xiaomi Mi TV 4S 65" L65M5-5ASP don't support Dolby Vision HDR format.
Many TCL TVs -- including some TCL TVs smaller size than 65" -- have Dolby Vision support.
If you're a heavy Netflix user --
it may be advisable to buy a TV that supports Dolby Vision.
Many heavy Netflix users want to watch their shows in Dolby Vision on their TV.
If nothing else, you may not feel physiologically bad every month knowing you pay the same Netflix fee as everyone else -- but can't enjoy your Netflix shows in Dolby Vision.
Even if you're not a Netflix user now -- it doesn't mean you won't start to subscribe to Netflix in the future.
Of course besides Netflix, there are other streaming services like Amazon Prime video, Disney+ etc.
If you're a heavy Amazon Prime video user,
then the Xiaomi 65" L65M5-5ASP is just nice --
because it has HDR10+ support:

If you don't use Netflix or Amazon Prime or any streaming services, then I guess you may not need to care about any of the above.
If you pay more for your TV, of course you expect more warranty coverage. Nothing special here.
