Within those 4 nations only England and Wales voted to leave ....

England, Scotland, Wales and N. Ireland did not vote on whether or not to leave the EU. The referendum was held in the UK - a single entity. If the constituent countries are considered separately from the UK, then the Greater London region should also be considered as it had a larger electorate than Scotland and N. Ireland put together and voted 60%/40% to remain.

..... but, sadly, it applied to the whole of the UK.

Brexit is not being applied in Northern Ireland in the same way as in Great Britain. There is a de facto customs border in the Irish sea between NI and the rest of the UK.
