Well, such photos do exists. Kind of. And several exists of them in Norwegian use!
There are a few photos that show the German insignia were at least partially overpainted on one plane at the capture site. But we do not know if they were fully overpainted and if Norwegian insignia was applied at the original capture site.
What is know is that the two captured planes were flown to Skattora seaplane base at Tromsoe where they were repainted in a grey colour overall (a war diary entry and photos prove this) and had Norwegian flag stripes applied.
Here are a few photos showing one of the captured planes with overpainted swastika and partially overpainted individual letter and some profiles detailing the colour schemes of the two He 115 Bs.
Source of photographs is Norwegian Defence Museum and the profiles are mine.
