Sony Xf-90 and HDMI questions

[Andy Pandy]

Hi all. I have just bought a Sony XF-90 tv and I am very happy with it. The tv says that only 2 of the 4 hdmi ports can do full 4k HDR and these ports are HDMI 2 and HDMI 3. I have my soundbar connected to HDMI 3 as this one says arc on it and my PS4 pro connected to HDMI 2.

For my 4k blu ray player will it still work to its full potential on HDMI 1 or HDMI 4? Or to ask a different question, would my soundbar still work as it should if I didn't plug that into the HDMI arc port?

Thanks

Im pretty sure that in the Sony settings on the TV when I turned something on to make the hdmi ports full speed it says ports 2 and 3 are full speed. On the back of the TV it says hdmi arc is port 3.

It's an LG soundbar I have. I don't think it's 4k ready though. I got it 3 years ago for £200 when I bought a £450 LG 4k tv. It does have hdmi in and hdmi out ports on it though.
