Same applies.
You only need to upgrade if you absolutely need HDR, or you don’t already have one.
New wi-Fi: no one complained about the old Wi-Fi. If your connection was slow on the old one, it’s going to be slow on the new one. You’re using it to stream Netflix.
New Bluetooth: again, same as Wi-Fi.
New processor: with worst graphics.
updated HDMI: which will only be useful if you have a TV that supports high frame rate, you have content that is high frame rate, and you need HDR. The majority of people have none of that.
So I say again, no need to upgrade unless you absolutely need HDR, or you don’t already have one.
