Yes, you can get 60°C flow from an air sourced pump but the CoPs drop significantly - 3 to 1 is probably realistic at that high a flow temp, even with fairly warm (i.e above 10°C) intake air.
I’m no expert - just an “interested” owner of a heat pump system but I’ve posted quite a bit of data on these because there is much more to sizing a heat pump than just looking at the “headline” CoP and max heat output figures.
That said, although they are not perfect air source heat pumps are a good way to heat a home if you want to have a moderately “eco friendly” solution.
I’d be very interested to know the exact model of the LG you mentioned - at some point I’ll be looking to change the boiler in the UK and had started to toy with whether I could make a heat pump work here, having access to a high flow temperature if it does not impact efficiency too much moght be useful.
