I own the 65" Sony OLED Bravia 8. Less than 1 year old.
Just FYI. For some unknown reason, Sony limits its ethernet port speed to 100 Mbps. The WiFi 6 antenna is capable of much higher Mbps than that. So unless you have interference issues, you are much better off using the WiFi 6 antenna rather than the hardwired ethernet port. Sony Picture Core movies require the WiFi connection for full resolution streaming.
Also, as some have already mentioned. I would invest in an AppleTV4K box. If you use the AppleTV app on the Bravia. It is limited to 25 Mbps. However all of the AppleTV original programming stream at much higher bit rates. The AppleTV4K box is capable of streaming up to 40 Mbps. Any AppleTV original or any movie rented/purchased through AppleTV will automatically be streamed at the higher bit rate when streamed using an AppleTV4K box.
One warning about setup. The AppleTV4K processor does all of the audio decoding inside the box and outputs LPCM audio. So your home theater amp or TV must be set to accept LPCM as opposed to bitstream input. The AppleTV4K box makes a substantial difference in quality. Especially immersive audio formats.
Just some information that you might want to consider. I hope that it helps.
