The first two probably Dyseriocrania subpurpurella - http://ukmoths.org.uk/show.php?id=1693 - and the second two probably Brindled Pugs - http://ukmoths.org.uk/show.php?id=698

So.... is image 2 simply Eriocrania subpurpurella moths have metallic golden wings, lightly speckled with purplish or blue tiny spots
while image 1 is this:
The relatively uncommon form fastuosella is much more richly marked with purple spots or striations.
Hmmm complicated, but I guess image 1 + 2 are the same, relatively speaking.

I don't think so. Forms should not really be treated in the same way as subspecies in birds. There is more routine variation. The key in MOGBI Volume 1 page 157 describes all subpurpurella as 'forewing golden with faint paler markings, usually with scattered purple and blue scales' and distinguishes the species from all other Eriocraniidae on the basis that those have a 'forewing purple, or golden strongly mixed with purple'.
The form fastuosella is described as 'forewing heavily strigulated purple and blue'. I wouldn't say the odd purplish scale fits that. So 1 is within the variation of the normal form in my view.
