Can't help that much... Some random thoughts anyway...
1- The lens flare effect that can be seen on the n°"...933" is consistent with what one could expect from a classic lens flare reflection, through a
central inversion point and from very bright lights that hit the ccd sensor:
Known example:
There's a little margin error due to the resizing.
So, yes, this can be added using Photoshop, but can also be the result of very bright lights coming from a 'solid' object.
2- The size (1181*787) is consistent with a JPEG 3:2 ratio (1.5), that gives not exactly 1.5, but 1.5006 which is very close, the margin error being
due, here again, to the resizing process that was applied to the original photos.
Here are the images sizes available for this camera and 3:2 aspect:
• 5184 x 3456
• 3456 x 2304
• 2592 x 1728
• 1920 x 1280

3- In the "...935" picture, there's a bright halo surrounding the whole object, except in some areas above that are darker:
....Plus it seems to have a faint 'flame' just below the object, could be a flare effect anyway.
Food for thoughts...
Edit to add point n°4:
The object in each picture is
perfectly centered... suspicious??
