That's where the attention to detail and QA comes in with the premium eyepieces...for a price of course. You might then be able to see deficiencies or aberrations introduced by your telescope...
Mass market telescopes are manufactured to be 'good enough'...so there's the risk of mirror defects, misalignments, poor blackening of surfaces, etc, etc. They're built to a price, it's the same as everything else.
Then there's the aberrations introduced because of the telescope design. In a fast Newtonian this is usually coma, fast refractors and cassegrains it's field curvature. Your Mak should be coma free but it might be possible to see some field curvature.
If you ask many here, the value of equipment, be it eyepieces, visual aids or whatever, it usually amounts to more than the value of the telescope
just feel free to ask folks opinion or experiences...there might be someone in the forum with the same or similar combination
Great pic, btw
