Micro for ID

This tiny micro [FL 7mm] was in our trap close to oak woodland 2 nights ago.  Unfortunately rigor mortis set in after a night in the fridge to placate it sufficiently to photograph!  On gross inspection the forewing was golden-coloured and under the hand lens there some was some purplish speckling. I believe this to be the leaf-miner, Dyseriocrania subpurpurella, but would be grateful of verification / correction.
