I don't know of any current, display pilots in the UK that fly PPM, and the truth is that if you go to a UK jet meet or public display, there are almost NO radio problems.
Mick Reeves uses Multiplex.
Away from jets, top scale modellers like Duncan Hutson and Len Gardner use Multiplex, Duncan Hutson adores the PPM failsafe.
No-one bought PCM radios. What they paid for was a sytem that did not glitch and lose points in a competition flight, or could be failsafed for public demos. None of us really care two hoots if the radio is PPM or PCM or morse code or smoke signals, if the end result does what we want. What people bought was failsafe because that's what gives them the result they want. It just happened to be on PCM so that is now very widespread. Failsafe on PPM is very new so naturally you will see very little of it. That doesn't make it any less good than PCM failsafe.
