It's almost as if the pads or something is knocked into a more locked in position when I pedal a bit and it stops the noise immediately.
I have no idea whether this is possible but maybe the wheel is slightly misaligned and pedalling a bit is enough to pull it straight.

I have this issue currently with a leaky Shimano caliper (going to replace it with Hope as I'm fed up).
Heat does indeed kill the noise for a wheel, I don't know why.
Contaminated pads - my current pre-ride routine demands I sand down the top layer of the pad which has got contaminated, and clean pads and rotors with IPA (not that kind). It's fine for a ride and then the caliper leaks again.

Also, what's the lever throw like on the new Ultegra Di2/hydro levers? Mine are shit.
I will let you know about R8070 soon
Bin the pads, clean rotor with acetone, you might've picked up oil from the road.

I think my rear brake setup is contaminated with oil - it squeals super loud.
Why though, would the squeal stop as soon as I pedal a little bit (still with the brakes on)?

Regarding contaminated pads - can they be saved? Disc cleaner didn't do shit.
