Absolutely stunning photographs of a beautiful insect!
It could be, although it
indica Schrank, 1802 is synonymised under
indigotea Dufour-Perris, 1840.
The key character (in Linsenmaier 1997) separating this species from
Chrysis iris is the colour of the middle scutal field compared to the lateral fields, do you have any picture straight from above? To me it seems the 2nd picture shows it as similar to the lateral fields and the 3rd it is darker than the lateral fields, so I cannot really give you an answer
