Good evening my DJI folks, it seems that my gimbal isn't going all the way straight down. Is there any way to check this problem out. Thanks

Hi there, my apologies for all the trouble. Did you experience any hard landings or crashes prior to the problem? Did you receive an error message on the APP? If yes, please provide a screenshot for further checking. Kindly restore the settings of your aircraft to factory defaults and  flash the firmware using DJI Assistant 2. Please download the software here: https://www.dji.com/spark/downloads and follow the video tutorial below. Thanks for your support.

can you share some fotos?

IF I am not mistaken it, the gimbal itselfs goes down "just about 80-85°", not real 90.
Just the viewing angle of the cam gives it a glimpse direct under the bird

Here are a couple of pictures

I see what you mean.
I did a -75° video and got this:

You might try that gimbal adjustment in the camera settings:
But I have only had to do roll adjustments and have no idea what you may be getting into with a pitch adjustment:
This is an older video and some menu items may be different but still in there

in sport mode the gimbal does not go all the way down, if you had been testing it in sport

Thank all of you for ideas.  I have never had the nerve to fly my spark in sport mode. I have never messed with any of the settings from when I took it out of the box. Just try to have fun flying and taking photographs.
