Hmmmm, would love to see the cost of the exotic cooling solution on the PS5. Surely going from copper heatsinks and thermal paste the silver plated custom shaped heatsinks and Liquid Metal in an entirely new process isn't cheap.
That said, how does one go about replacing the LM if ones console starts to become noisy or some other unforseen issue arises? Is it a simple process like with replacing thermal paste on the old consoles? There is obviously far more risk this time around if that LM leaks on to the other components or MB but i'd be interested to see what the process is.

you're probably the best person to ask about the above question.
Silver coating won't add much cost, it's pretty much a a very thin layer probably around the APU area and where the liquid metal is applied. Now we need to know if Sony came up with its own liquid metal compound, and if it's patented or not. If it's using 3rd party liquid metal then that's good.
My speculation about how you change the LM is like this:
Wait for the console/heatsink to reach the temperature needed for the compound to solidify, then remove the heatsink:
Before removing the LM sealing/gasket, remove the LQ heating it up a little and use a syringe to suck it out, and a napkin for the rest.
Use a hairdryer to heat the new LM and use another syringe to apply it in the very middle then gently spread it evenly across the APU on an evenly balanced table. Try to cool the compound enough so it solidifies before putting the heatsink again.
And you're good to go. That's my speculation, not hard, but needs attention. If the bracket/gasket doesn't look good enough, probably replace it as well before reapplying it, and that piece should be provided by Sony directly which might tie you to fixing it in a certified Sony workshop.
Overall, I think you'll never need that, and it should last beyond next gen cycle.
