My 2c.
Cumulative error?. Your rims appear to be differing types as are your tyres? Yes?
Image perspective may not be square on?
Unless it is a 'funny bike' for a sideshow all slight variables can be compensated for with height/angle adjustment.
Why to the bike shop?
Does it ride well, no dropping to one sides, keeps a straight line?
Save yourself some time, money and possible jesting(?).
Do you have a tape measure?
If you are wanting some perfection, use Pythagoras (3,4,5) to check for square (or a square, or level).
You do not require a perfect level surface; a 180 degree flat surface is all you require.
