The left speaker should be equidistant from the center TV screen, compared to the right, and based on the 2nd picture you show, above, it does not appear to be. [The goal is bi-lateral symmetry with the center of the TV on the same axis.] The main audio rack and the left speaker should therefor swap positions to correct this.
This may place the L and R speakers slightly closer to each other than you are used to, but that is far less objectionable than the first fault and actually may improve the tightness of imaging (localization) at the expense of a slightly narrower sound stage. Give it a go and see what you think. You can easily switch back if you don't like it.
As a less important refinement I would also advise placing the three front speakers at a more similar tweeter height. That would mean having to buy new stands, but in the interim you could at least attempt to improve matters by moving the tweeters a few inches downward, simply by flipping the L and R speakers upside down. [This should make lateral panning of sounds across the front sound stage better and not seem to dip downward in the center, yet peak upward when at the sides, making a "smiley face".] Again, free of charge to try out and you can always switch back if you don't like it. [There's no rule tweeters must be on top, it is simply a design trend, and if you don't mind the looks you can simply leave it that way].
Obviously if you make any of these alterations it also means having to re-run Audyssey calibration. Don't even think about making these changes and attempting to listen to the results without re-running the calibration first.
