Same TV we have. Still prefer our AppleTV 4k (1st gen) even though the LG’s streaming functionality is quite adequate in most regards. The ATV tends to get the latest versions of most streaming apps sooner, with maximum functionality (UHD content, Dolby Vision, Atmos, etc.). Its interface is still snappier, less cluttered, and devoid of advertising. And oh, those screen savers! All that said, I think I could live with the LG’s WebOS alone if I had to. It’s reasonably OK.

Also note that you don’t need an AppleTV to get an AppleTV+ subscription. The AppleTV+ app is available on most streaming platforms (Roku, Fire, etc.).

Personally, though, I endorse the AppleTV as a great device. I’ve had my 4k version for several years, and it shows no sign of obsolescence and outperforms my FireTV Max and the WebOS platform on my LG C2. It’s smoother, faster, more stable, and utilizes all the features — UHD, Atmos, etc. — available on each service. (Exception: there are some X-ray/bonus features on certain Prime shows only viewable on a FireTV.) You can count on getting the best available picture and audio quality from each service on an AppleTV, IMO.
