To start with, I suggest installing the self-hosted OpenSpeedtest App on one of the wired PCs. This will let you run speed tests within the network to that PC. Try also running a continuous ping test from the HTPC to both a PC and the router, e.g. two minimised command prompt windows while you are streaming TV in the living room. When your streaming services start giving issues, run a speed test from the HTPC or the affected phones to that PC.
If the speed test is very low, e.g. under 20Mbps (4K typically requires 10 to 20Mbps sustained throughput per stream), then this confirms the wireless backhaul is the problem. If the speed is fine, have a look at the two command prompt windows for any ping spikes (over 10ms) or times outs. For example, if the window pinging the router has ping spikes or timeouts, but not the window pinging the PC, this indicates a problem with the Gigabit Powerline.
It would also be worth trying speed tests between the two Powerline adapters in the evening vs. the day. For example, it is quite possible that various electronics switched on in the evening is reducing the Powerline performance due to the additional electrical interference, especially from LED lighting.
I would avoid adding another Gigabit Powerline as this will reduce the performance of the Powerline network. Instead, you can try swapping the primary MW6 node with the Living room MW6 node and connect the Powerline adapter to it. With the nodes swapped you can connect the two PCs to the two ports of the MW6 node.
