BRINDLED OR OAK-TREE ? ... What do YOU think ?

Yesterday I posted two pics of Brindled Pug, but sharp-eyed Matt ( Captain Trappings) is 100 per cent sure
that  the top picture of the two is in fact an Oak-tree Pug.
Opinions are very welcome .......

Oak-tree suspect

Brindled Pug

 The discal marks are wider in the top pic, the bottom Brindled shows a thin, short black line.
There are orange/brown scales along leading and trailing edges of  forewing in the top pic which point to Oak-tree (click to enlarge).
There is a subtle difference in wing shape, but they are more or less similar in wingspan, about 23 mm give or take a mil.
Anyone ?
