Thanks!
I have lightened and reloaded the photos. I looked and couldn’t find any ridge along the head. If you need more pics from different angles, let me know. I hope this helps!

Two suggestions
Could be a mid-minor male O. taurus. Their horns range from water buffalo size to barely detectable. That species has a transverse ridge across the top of the head, which you should be able to spot under slight magnification. O. gazella is another two-horned possibility, but they have some elytral patterning.
Try getting a brighter image so the colors are more visible.

O. striatulus
, not
O. gazella
