Wheatear - but is it a different type??

Observation - Wheatear - but is it a different type?? - UK and Ireland. Description: We came across this Wheatear while walking up a coastal hill in Woolacombe, north Devon. It was not bothered by us at all, which could've been down to complete exhaustion from a long migratory flight? What I'm not sure about is if this is 'just a Wheat

We came across this Wheatear while walking up a coastal hill in Woolacombe, north Devon. It was not bothered by us at all, which could've been down to complete exhaustion from a long migratory flight?

What I'm not sure about is if this is 'just a Wheatear' or a different kind? Isabelline? Desert?
Probably getting my hopes up, but if anyone can confirm/deny for me please?
Thanks.
