I did some checking on this and it should be
C. harmodius martinus after all.
Even if there is excessive blue tone, & if this removed it would not show the steely grey tone of
C. bernardus.
Here are examples of C. harmodius this probably from Thailand.
In particular, note the shape of the hindwing submarginal markings.

Here is one from Java. You can see the hindwing upper white spots are variable. & smaller here.

Your shot matches these well especially the submarginal markings in pic 1.
